Copper strip is a kind of metal component, the product specification is 0.1-3 & times; 50 ~ 250mm copper strip products in various states. Copper rolled products with a thickness of 0.06-1.5mm are called copper strip. At present, the maximum thickness of the strip is 2mm and the maximum width is 600mm. The length of the strip is generally only the minimum length according to the standard, and it is supplied in coils. The professional uses of the copper strip are different due to the different materials of the copper strip. The professional uses of the common grades of copper strip are as follows.

Hsn60-1: good mechanical properties and machinability, commonly known as naval brass ship parts or other parts in contact with seawater.

Hsn90-1: with high corrosion resistance and antifriction, it is the only tin bronze that can be used as antifriction alloy. It is used as corrosion-resistant and antifriction parts such as bushings.

Aluminum brass strip

HAl77-2: high strength, high hardness, good plasticity, good corrosion resistance in seawater, but with corrosion cracking tendency. It is used for condensing pipes and other corrosion-resistant parts in ships.

Hal67-2.5: good wear resistance, good corrosion resistance to sea water, corrosion-resistant parts of seagoing ships.

Hal60-1-1: high strength, slightly poor plasticity in cold state, good corrosion resistance and sensitive to corrosion cracking. It is used for various corrosion-resistant structural parts, such as gears, shafts and material sleeves.

Hal66-6-3-2: it has high strength, hardness and wear resistance, good corrosion resistance, but poor plasticity. It is a nut under large worm and heavy load working conditions.

Manganese brass strip

Hmn57-3-1: structural parts with high strength and hardness but poor plasticity and better corrosion resistance than ordinary brass.
