Profile: Shenzhen and Shuo Metal Co., Ltd. is a supplier of resistance welding electrodes for spot, projection and seam welding machines. Our products are used in automatic welding applications, as well as in manual stations. We manufacture according to the existing documentation provided by the customer, or based on the submitted sample parts in case the manufacturing drawings are not available. We are specialized in the production and operation of resistance welding electrode materials, electric spark electrode materials, and hardware mold materials. C18150 chromium zirconium copper is a unique copper alloy with high electrical conductivity, hardness, and ductility, moderate strength & excellent resistance to softening at elevated temperatures. C18150 can provide less sticking and resisting deformation, longer than its C18200 counterpart in some specific situations. Beryllium copper is an important conductive and elastic material with a number of outstanding properties of high conductivity, fatigue resistance, high strength, high elasticity, little elastic lag, corrosion resistance and no spark under impact. This material is commonly utilized for its highest strength and hardness compared to commercial copper alloys.
