Ferrous Scrap

Heavy Melting Steel (HMS)

Ferrous scrap is any discarded or recycled material primarily composed of iron and steel.
Distinguished by its magnetism and durability, ferrous scrap is the most commonly recycled

Ferrous metals are used in a vast range of products, and their scrap is often categorized
based on its source and composition.

Heavy Melting Steel (HMS):

Comes from thick, heavy steel such as beams and industrial equipment from construction and demolition.

Cast Iron Scrap:

Recycled cast iron from automotive parts, machinery, and cookware.

Auto Scrap:

Vehicles that have been salvaged for their steel and iron content.

Industrial/Prompt Scrap:

Leftover metal from manufacturing processes and factory production.

Light Metal Scrap (LMS)

Ferrous light metal scrap” refers to relatively thin or light-gauge steel and iron scrap, such as sheet metal, pipes, and appliance parts, which are magnetic due to their iron content. While less dense than heavier ferrous metals, this type of scrap is highly valuable for recycling due to its widespread use in consumer goods and industrial applications, and its magnetic property allows for easy differentiation from non-ferrous metals

Non-Ferrous Scrap

Aluminium Scraps

Aluminium UBC, or Used Beverage Container, refers to the
high-quality Aluminum scrap collected from recycled drink cans. This post-consumer
material is a highly valuable commodity in the recycling industry due to its purity and
endless recyclability.

Aluminium Extrusion 6063

Aluminium Extrusion 6063 Scrap is a valuable type of commercial Aluminum scrap typically sourced from window frames, door frames, and architectural structures. Its value is primarily determined by its purity and the presence of contaminants like paint, iron, or plastic.

Material composition

The material is based on the 6063 Aluminum alloy, known for its corrosion resistance and good surface finish.

Main elements

Silicon (Si) at 0.20–0.60% and Magnesium (Mg) at 0.45–0.90%.

Contaminants

Iron (Fe) content should be a maximum of 0.35%, with other elements like copper, zinc, and manganese also tightly controlled.

International standards

The Institute of Scrap Recycling Industries (ISRI) specifies grades for Aluminum scrap, and the code for 6063 extrusion scrap is TATA

Aluminium Alloy Wheels

Aluminium alloy wheels are vehicle wheels made from an alloy of aluminium mixed with other metals, like nickel or magnesium. Aluminium alloy wheel scrap, known by the ISRI code “TROMA,” is a valuable, non-ferrous metal widely recycled for its high Aluminum content. The recycling process for Aluminum alloy wheels is highly energy efficient and has significant environmental benefits

Aluminium Casting Scrap

Aluminium casting scrap is waste material from manufacturing processes or discarded products that is melted down and reused, which offers significant economic and environmental benefits. The value of the scrap depends on its purity and alloy composition.

Clean casting scrap:

This is free of contamination like paint, steel, or non-metallic parts. Because it requires minimal processing, it is one of the most valuable grades.

Dirty or mixed casting scrap

This contains non-metallic components like steel bolts or rubber bushings, or has been painted or coated. It must be sorted and cleaned before being recycled, which lowers its value.

Diecast scrap

This is generated specifically from die-casting operations and includes defective products or off-cuts. Its alloy content can vary significantly depending on the industry.

Automotive scrap

A significant source of casting scrap is discarded vehicle parts, such as engine blocks, cylinder heads, and transmission cases.

Aluminium Ingots – A7 Grade

Aluminium A7 ingots are a high-purity, primary Aluminum grade prized for their versatility, quality, and specific chemical composition. The designation “A7” signifies a minimum Aluminum content of 99.7%. The ingots are produced through the smelting and casting of refined alumina derived from bauxite ore.

High purity

A minimum of 99.7% Aluminum content with very low levels of impurities like iron (Fe) and silicon (Si).

Lightweight

Like other Aluminum products, A7 offers a high strength-to-weight ratio, which is crucial for reducing mass in manufacturing applications.

Corrosion resistance

Aluminum naturally forms a protective oxide layer that shields the metal from the elements, ensuring long-term durability.

High thermal and electrical conductivity

These properties make A7 suitable for components requiring efficient heat dissipation or electrical transmission.

Recyclability

Aluminum is highly sustainable and can be recycled repeatedly without a loss in quality, making A7 an environmentally friendly choice.

Malleability and formability

The material can be easily shaped and formed for various manufacturing processes.

Copper Cathode

A copper cathode is a form of high-purity copper produced through the electrolytic refining of copper ore. These large, rectangular plates, with a typical purity of 99.99%, serve as the primary raw material for manufacturing a wide range of copper products.

Production process

The production of copper cathodes involves several stages, which differ depending on the type of copper ore (sulphide or oxide).

Mining and concentration

Copper ore is first extracted from a mine, crushed, and ground into a powder. The copper-containing minerals are then concentrated into a slurry.

For oxide ores (hydrometallurgy):

1) The concentrated ore undergoes leaching, where a weak acid solution dissolves the copper content.
2) The resulting copper-rich solution is then treated in a process called electrowinning. An electric current causes pure copper to deposit onto starter cathode plates, resulting in a high-purity product.

For sulphide ores (pyrometallurgy):

1)The concentrated ore is processed in a smelter at high temperatures to produce blister copper, which is about 99% pure.
2) This blister copper is cast into large anodes and placed in an electrolytic bath.
3) Through electrolytic refining, an electric current moves copper ions from the impure anode to the pure copper starter sheet (the cathode). Impurities settle to the bottom as "anode slime

SS 304

Stainless steel 304 scrap is a valuable, non-magnetic scrap metal that is widely recycled for its high nickel and chromium content. The price fluctuates based on global commodity markets and the scrap’s quality.

Corrosion resistance: Grade 304 is composed of approximately 18% chromium and 8% nickel, which provides excellent resistance to corrosion.

Recyclability: It is 100% recyclable. Recycling stainless steel reduces the need for virgin materials and helps cut down on energy consumption during manufacturing.

High alloy content: The nickel and chromium content are valuable in the scrap metal market and fetch a higher price than common ferrous scrap.

SS 316

Stainless steel 316 scrap is a valuable, non-magnetic scrap metal known for its high corrosion resistance, which is primarily due to its molybdenum content. This makes it more valuable than the more common 304 stainless steel. It can be recycled for use in various industries, including marine, chemical processing, and medical manufacturing.

Composition

316 stainless steel contains 16–18% chromium, 10–14% nickel, and most importantly, 2–3% molybdenum. It is the added molybdenum that sets it apart from grade 304, providing superior resistance to chlorides and other corrosive chemicals.

Higher value

Because of its higher nickel content and the presence of molybdenum, 316 stainless steel scrap fetches a higher price than 304 grade.

Non-magnetic

As an austenitic stainless steel, grade 316 is non-magnetic. You can use a magnet to help confirm its non-magnetic properties, which distinguishes it from lower-value, magnetic stainless-steel grades like 430.

Testing for molybdenum

If you are unsure whether a piece of stainless steel is 304 or 316, you can purchase a molybdenum test kit. The test involves applying a testing solution that reacts with the molybdenum in 316, causing a brown stain to appear. If it is 304, there will be no reaction.
