At present, the recycling price of scrap copper is determined according to the copper price of Yangtze River futures. Scrap copper is divided into copper and brass, and the prices are different. There are many kinds of copper and 22.5 brass, and the price is around 14- 18 yuan.
There is no standard for scrap copper in China, but with the acceleration of industrialization in China, the social and economic environment faced by the recycling, trading and recycling industries of scrap nonferrous metals has changed greatly, not only the variety composition of scrap nonferrous metals has changed greatly,
Moreover, a large number of foreign waste non-ferrous metals and various available wastes have flooded into China, which has provided a rich source of raw materials for the production of non-ferrous metals in China, and also put forward new requirements for the production and processing of recycled non-ferrous metals.
Brass classification:
Lead is actually insoluble in brass and distributed on grain boundaries in the form of free particles. Lead brass can be divided into α and (α+β) according to its structure.
Lead is actually insoluble in brass and distributed on grain boundaries in the form of free particles. Lead brass can be divided into α and (α+β) according to its structure.
α lead brass can only be cold deformed or hot extruded because of its harmful effect and low high temperature plasticity. (α+β) lead brass has good high temperature plasticity and can be forged.
