Scrap metal (scrap metal)

Scrap metal (scrap metal) – the general, collective name of various metal debris (metal products that have become unusable) disposed of or not disposed of in the secondary metallurgical cycle. Most often, scrap metal includes metal garbage specially concentrated in designated areas for subsequent processing or disposal.

Types of scrap metal

Scrap metal is divided mainly by the type of metal that has a predominant percentage in the composition of scrap metal, or a predominant economic value in the processing of scrap metal.

Scrap and waste of non – ferrous metals and alloys are divided into:

by metal names;
according to physical characteristics – for classes;
by chemical composition – into groups and grades of alloys;
according to quality indicators, it is divided into varieties.
Secondary ferrous metals are divided into:

by carbon content – into two classes;
by the presence of alloying materials – into two categories;
according to quality indicators — by 28 types;
according to the content of alloying elements – by 67 groups.
In economic activity, industry and trade, letter designations of types and groups of scrap metal are widely used, which are introduced in each state :

Ferrous scrap (scrap of ferrous metals)
Iron scrap: chips, scale, casting waste, products that have spent their service life.
Cast iron scrap: shavings, casting waste, etc.
Stainless scrap: metalworking waste, used products.
Non-ferrous scrap (non-ferrous metal scrap)
Copper scrap: metalworking waste and other waste.
Scrap of copper alloys: waste from copper alloys (brass, bronze, volumes).
Aluminum scrap: all kinds of scrap aluminum and its alloys.
Magnesium scrap: aircraft scrap.
Titanium scrap: aircraft and ship scrap of titanium alloys.
Lead scrap: battery and cable.
Rare metal scrap: scrap of complex alloys and waste from high-tech industries.
Semiconductor scrap: waste from the electronic industry.
The value of scrap metal recycling

Recycling of scrap metal is of great economic and environmental importance. Since, taking into account the modern industrial development of the world and the volumes of metal involved in industrial use, it becomes clear that the volume of metal is enormous, then the volumes of scrap metal constantly entering the scrap are also very large. Based on this provision, metal waste recycling facilities have existed in many countries for more than a hundred years.

The main incentives and benefits of recycling scrap metal of all types:

reduction of the load on metal deposits (by now severely depleted);
improving the environmental situation;
reduction of fuel volumes for the production of the most important metals;
reducing the scattering and sputtering of metals on a global scale.
