What material corresponds to the grade of chromium zirconium copper? Characteristics and applications
Chromium zirconium copper (rr) Chemical composition (mass fraction) (:., r:.) Hardness Conductivity/Softening temperature ℃
Features: It has relatively It has high strength and hardness, electrical and thermal conductivity, good wear resistance and wear-reducing properties. After aging treatment, the hardness, strength, electrical conductivity and thermal conductivity are significantly improved, and it is easy to weld. It is widely used in motor commutators, spot welders, seam welders, butt welder electrodes, and other parts that require strength, hardness, conductivity, and conductive pad properties at high temperatures. The electric spark electrode can be used to electrically etch an ideal mirror surface. At the same time, it has good upright performance and can accomplish effects such as thinning that are difficult to achieve with pure red copper. It performs well on difficult-to-process materials such as tungsten steel.
Chromium zirconium copper has good electrical conductivity, thermal conductivity, high hardness, wear resistance, explosion resistance, crack resistance and high softening temperature. It has low electrode loss during welding, fast welding speed and low total welding cost. It is suitable for welding. The electrode of the welding machine is related to pipe fittings, but its performance on electroplated workpieces is average.
Application: This product is widely used in various materials for welding, contact tips, switch contacts, mold blocks, and welding machine auxiliary devices in machinery manufacturing industries such as automobiles, motorcycles, and barrel making (cans).
Specifications: Rods and plates have complete specifications and can be customized according to customer requirements.
Quality requirements:
. Use eddy current conductivity meter to measure conductivity, measure three points and take the average value
. Hardness is based on Rockwell hardness standard, take three points and take the average value
.Softening Temperature test, after the furnace temperature is maintained at ℃ for two hours, the quenching water cannot be lowered than the original hardness after cooling
Physical indicators: hardness, conductivity:, softening temperature: ℃
Resistance welding electrode:
Chromium zirconium copper ensures its performance through a combination of heat treatment and cold working. It can obtain the best mechanical and physical properties, so it is used
as a general-purpose resistance welding electrode, mainly as a low-cost spot welding or seam welding electrode. The electrode of carbon steel and coated steel plate can also be used as the electrode handle, shaft and gasket material when welding low carbon steel, or as the electrode handle, shaft and gasket material when welding low carbon steel, or As large molds and fixtures for projection welding machines,
molds or embedded electrodes for stainless steel and heat-resistant steel.
EDM electrode: Chromium copper has good electrical and thermal conductivity, high hardness, wear resistance and explosion resistance. When used as an EDM electrode, it has the advantages of good uprightness, non-bending when thinning, and high smoothness.
Mold base material: Chromium copper has the characteristics of electrical and thermal conductivity, hardness, wear resistance and explosion resistance, and its price is superior to beryllium copper mold materials. It has begun to replace beryllium copper as general mold material in the mold
industry. For example, shoe sole molds, plumbing molds, plastic molds that generally require smoothness, connectors, guide wires, and other products that require high-strength wires.
