Large plain washers for self-tapping screws

The main material of purple copper gasket is purple copper, also known as copper ingot. Purple copper is a copper alloy containing more than 95% copper, and other components include tin, lead, zinc and other small elements. Purple copper gaskets are often used in electromechanical, electronic and automotive fields. Their main function is to form a gap filler between two contacting surfaces in order to produce a degree of contact between the two surfaces and to distribute the pressure. By using purple copper gaskets, damage to structures or repair work can be avoided.201 304 316 301 Stainless steel gasket washer Brass gasket Purple copper gasket Phosphor bronze gasket H62 brass gasket, Aluminum gasket, Iron gasket, Red steel paper gasket, Ship engine cylinder gasket, etc. Copper gasket, washer, round piece, arc piece, oval piece, plum blossom-shaped piece, punching piece, gear piece, square piece, cross-shaped piece.

Performance characteristics: normal use temperature of 620 ℃, not annealed copper hardness, annealed copper gasket hardness becomes lower, better elasticity, you can make the compression surface more tightly, without leaving gaps, commonly used in ordinary and high-temperature and high-pressure environment seals used. Brass hardness is higher, good performance, generally used as a connector for equipment. Copper and brass have good performance in acid and alkali environments.    

Purple copper washers are a kind of commonly used sealing gaskets, which are widely used in machinery, electronics, automobiles, and other fields. The hardness of copper washers is generally between RB45 ~ and RB70, with sufficient strength and plasticity, able to withstand greater pressure and deformation. In addition to hardness, copper washers have some other performance parameters, such as corrosion resistance, electrical conductivity, thermal conductivity, processability, and sealing. Among them, sealing is one of the most important performance parameters of copper washers, and its sealing reliability determines the application range of the washers in mechanical equipment. Purple copper washers have a wide range of applications in machinery manufacturing, electronic components, automotive parts, aerospace, and other fields. Such as in the field of aerospace, copper washers are widely used in rocket propellers, spacecraft, satellites, and other high-intensity, high-temperature, high-pressure applications; in the field of automotive components, copper washers are commonly used in automotive engines, pumps, compressors, brake systems and other important parts of the seal.
