Aluminum Scrap Descriptions

These specifications derive from the Institute of Scrap Recycling Industries (ISRI) and are internationally accepted and used throughout the world to trade commodities.

New Production Aluminum Scrap

Common Alloys: 5052, 3003, 6061, 6063, 3105

Aluminum Clips

MIXED ALUMINUM CLIPS- Consists of new, clean, uncoated and unpainted aluminum scrap of two or more alloys with a minimum thickness of 0.15” (.38mm) and free of hair wire, wire screen, dirt and other non-metallic items. Oil and grease not to total more than 1%. Free from punchings less than ½” (1.27 cm) in size. 

SEGREGATED ALUMINUM CLIPS- Consists of new, clean, uncoated and unpainted aluminum scrap of one specified aluminum alloy with a minimum thickness of 0.15” (.38 mm) and to be free of hair wire, wire screen, dirt and other non-metallic items. Oil and grease not to total more than 1%. Free from punchings less than ½” (1.27 cm) in size. 

Aluminum Punchings & Stampings

Consists of new, clean, uncoated and unpainted aluminum scrap of two or more alloys with a minimum thickness of 0.15” and free of hair wire, wire screen, dirt and other non-metallic items. Oil and grease not to total more than 1%. 

Aluminum Extrusions

Consists of one alloy (typically 6063). Material may contain “butt ends” from the extrusion process but must be free of any foreign contamination. Anodized material is acceptable. Painted Extrusions (typically 6063) will have a lower value than Bare 6063 Extrusions.  

Aluminum Pucks

Consists of Aluminum Turnings which have been run through a compressing machine. The machine squeezes out the cutting fluid and creates a product which looks like a hockey puck. 

Aluminum Turnings

MIXED ALUMINUM TURNINGS– Consists of clean uncorroded aluminum borings and turnings of two or more alloys and subject to deductions for fines in excess of 3% through a 20-mesh screen.  Material is to be free of dirt, iron, oil, moisture and all other non-metallic items.  

SEGREGATED ALUMINUM TURNINGS– Consists of aluminum borings and turnings of one specified alloy. Material should be free of oxidation, dirt, free iron, stainless steel, magnesium, oil, flammable liquids, moisture and other non-metallic items. Fines should not exceed 3% through a 20 mesh (U.S. standard) screen.  

Secondary Grade Aluminum Scrap

Common Alloys: 380, 319, 356, 360

Cast Aluminum

Consists of Casting Alloys such as alloys 380 and 319.  The material is to be free of oil and steel. 

Aluminum Cans

Consists of old aluminum food and/or beverage cans. The material is to be free of other scarp metals, foil, tin cans, plastic bottles, paper, glass, and other non-metallic items. 

Aluminum Wheels

Consists of clean, single-piece aluminum wheels of a single specified alloy, fee of all inserts, steel, wheel weights, valve stems, tires, grease and oil and other non-metallic items.   

Auto Scrap | Aluminum Breakage

Consists of all clean automobile aluminum castings of sufficient size to be readily identified and to be free from brass, bushings, and non-metallic items. Oil and grease not to total more than 2%.

Aluminum Radiators

Consists of clean aluminum and copper radiators, and/or aluminum fins on copper tubing, free of brass tubing, iron and other foreign contamination.
