Characteristics and application range of different grades of brass

Characteristics and application range of different grades of brass

Brass has high strength and hardness, electrical and thermal conductivity, good wear resistance and anti-wear properties. After aging treatment, the hardness, strength, electrical conductivity and thermal conductivity are significantly improved, and it is easy to weld. Widely used in motor commutators, spot welders, seam welders, electrodes for butt welders, and other parts that require strength, hardness, conductivity, and pad properties at high temperatures. The electric spark electrode can be used to etch an ideal mirror surface, and at the same time, it has good upright performance, and can achieve the effects that are difficult to achieve with pure red copper such as thin slices. It performs well on difficult-to-machine materials such as tungsten steel.

Characteristics and application range of H96 brass

H96 brass is composed of 96% copper and 4% zinc alloy. H96 brass has good cold and hot working properties, suitable for extrusion, tying, stamping, drawing, forging and other processing methods, easy to weld and tin plating; H96 Brass has high corrosion resistance in the atmosphere and light, and is not prone to stress corrosion cracking. H96 brass is generally used in currency; souvenirs; micro chapters; detonators; shells, enamel bottom tires, waveguides, heat pipes/sheets, conductive devices, etc.

Characteristics and application range of H90 brass

H90 brass is composed of 90% copper and 10% zinc alloy. H90 brass has good mechanical properties and hot and cold pressure processing properties. It is basically the same as H96. H90 brass is also suitable for upsetting, rolling and hot forging. Etc., good corrosion resistance, can be plated with gold, coated with enamel, etc. H90 brass is generally used in decorations, medals, marine components, rivets, waveguides, water tank belts, battery caps, water pipes, bimetals, etc.

Characteristics and application range of H85 brass
