- Representing Methods of Copper and Alloy Mark（GB/T340—1976）
According to the national standard GB/T340—1976, the representing methods of nonferrous metal and alloy mark are:
1.The name of product mark is represented by codename prefix or component figure after the element symbol or sequence number connecting with product type or group name....
- When taking care of copper plate, it should notice the following items
1. Copper plate put in the clean and dry room according to the component, mark, it can not put in the same storage with acid, alkali, salt.
2. If copper plate gets damp when transporting, it should be wiped by cloth or put after dry in the sun.
3. The storehouse should ventilate, coordinate...
- Copper Formula
1. All series single plate theoretical weight (kg) is about equal to thickness (mm) times width (m) times length (m) times density
2. All series single rolling panel theoretical weight (kg) is about equal to (OD plus ID) (cm) divided 2 times 3.1416 times strip width (cm) times strip rolling wall...
- Classification of Copper
It is red, so called red copper. The density of pure copper is 8.96, smelting point is1,083 degree centigrade, with good electric conductivity, heat conductivity, ductility and corrosion resistance. It is mainly used to make machine, bus, cable, switch settings, transformer and heat exchanger,...
