ACCEPTED MATERIALS

HMS is broken up into two major categories: HMS 1 and HMS 2. HMS 1 does not contain galvanized and blackened steel, whereas HMS 2 does.

P&S typically comes in the form of I-beam or plate over ½" thick. This is one of the highest grades of steel due to its 100% recovery when melted.

Applications can be solder, optoelectronics, tin plating, glass production, dental applications and tools, specialized alloys, wheels, machinery, construction materials, household appliances, and many more.

Shredded scrap is homogenous or a blend of iron and steel scraps which is magnetically separated. 

In the lifting and rigging industries, wire rope is attached to a crane or hoist and fitted with swivels, shackles or hooks to attach to a load and move it in a controlled matter. It can also be used to lift and lower elevators, or as a means of support for suspension bridges or towers.

Stainless steel is primarily made from medium and low-carbon steel and is broken into many grades.

Dirty Stainless (80%+) is for grades 304 and 316 that are contaminated by foreign material such foam, rubber, glues, grease, copper, brass, and iron. Foreign materials are not to exceed 80% of the total weight.

These are found in automobiles. and are made of aluminum casing with iron pulleys and other iron internals.

Separate them from dirty aluminum, as they are their own grade. 

Automobiles must be drained of all fluids. Before bailing, batteries and any lead switches must be removed. Upgrades can be aluminum wheels and catalytic converters

Aluminum wheels can be found on automobiles, lawn care equipment, trucks, and semis. Chrome alloy rims and semi wheels must be separated from other AL rims.            

Clean: They must be clean of valve stems, sensors, and lead weights.

Dirty: Rims that come in with lead wheel weights, rubber, steel, or brass valve stems, and plastic center cap. Brass valve stems can be upgraded to dirty brass. Lead weights are to be separated into its own category.

Made up of 47% - 48% copper and 52% - 53% aluminum. 

They will have CU tubing and AL fins. 

Clean: All foreign materials must be removed for this grade.

Dirty: Still have steel ends, foam strippings, and other foreign materials.

Inside an alternator you'll find a steel shaft that holds the rotor, mounted on bearings at either end of the shaft.

The rotor is made up mostly of wound copper, with a steel exterior,  inside the aluminum housing of the alternator is the stator, which is also made up of wound copper.

Lead acid batteries are made up of flat sheets of lead placed upright in a row with sulfuric acid surrounding them. 

When a battery is discharged, both positive and negative lead plates become lead sulfate, the electrolyte loses much of its dissolved sulfuric acid and becomes primarily water.

A starter (also self-starter, cranking motor, or starter motor) is a device used to rotate the  (crank) in a internal-combustion engine to initiate the engine's operation under its own power. 

Starters can be electric, pneumatic, or hydraulic.  

Copper starters are made up of copper windings encased in steel with an aluminum nose. They also have a small electric solenoid built into the starter casing. 

The most common type is alternating current (AC) with a cast-iron shell with roughly 8-10% copper recovery. 

This grade will consist of whole electric motors and/or dismantled electric motor parts that are primarily copper-wound. 

No excessive steel attachments such as gear reducers, iron bases, pumps, or loose free iron allowed. 

Sealed steel units are a compressor pump that enables the flow of the refrigerant. 

Reciprocating, rotary, and centrifugal compressors are the most common among refrigeration units. 

They are made of copper tube coils, e-motors, copper wire, and steel casing. 

A radiator is a heat exchanger that is used to transfer thermal energy from one medium to another for the purpose of cooling and heating. 

Radiators can be made of many types of ferrous and non-ferrous materials such as, aluminum, brass, copper, stainless steel, and iron.

They are typical use in industrial settings, mining machinery and equipment, oil and gas fields, fans, blowers, machine tools, turbines, pumps, power tools, compressors, alternators, rolling mills, movers, and paper mills.

High grade electronics are high reliability products that have a high recovery rate for non-ferrous and precious material. 

Mid grade electronics are dedicated service electronic products such as laptops, microwaves, televisions, tablets, MG boards, etc. This grade will have a higher recovery for non-ferrous material.

Low grade electronics are cheaply made high volume products that hold the lowest standard of quality, containing more plastic and other foreign materials than non-ferrous material.

A catalytic converter is an exhaust emission control device.

Aluminum oxide, titanium dioxide, silicon dioxide e.g. colloidal silica or a mixture of silica and alumina can be used. 

The catalyst can be made with many different precious metals such as platinum, palladium, rhodium, cerium, iron, manganese, and nickel.
