Zinc scrap

ZINC is a bluish white metal, which has similarities with magnesium and beryllium.

The most common alloys of zinc are with aluminum and copper, which improve the characteristics of zinc including its ability to be molded. It is also a lesser component in various alloys, mainly with copper as brass (3% to 45% zinc), alpaca metal (Cu-Ni-Zn) and bronze (Cu-Sn) for molding

We can find ZINC as:

Score – Zinc Dross – Old Die Cast – New Die Cast – Die Cast Dross – Ashes

Zamak is an alloy of zinc with aluminum, magnesium and copper.

It is a cheap and tough material, resistant to traction, having good mechanical resistance and the ability to change shape, and good filtering properties.

Zinc scrap can be classified as following:

Saves

OLD ZINC DIECAST SCRAP

Shall consist of miscellaneous old zinc base die-castings, with or without iron and other foreign attachments

Scabs

NEW ZINC DIECAST SCRAP

Shall consist of new or unused, clean, zinc base die-castings. Castings to be unplated, unpainted, and free from corrosion

Scope

NEW PLATED ZINC DIECAST SCRAP

Shall consist of new or unused clean, plated zinc base die-castings, free from corrosion.

Score

OLD SCRAP ZINC
