1.Beryllium copper Beryllium copper is a copper alloy with beryllium as the main alloying element. It is a supersaturated solid solution copper base alloy, which is a non-ferrous alloy with good combination of mechanical properties, physical properties, chemical properties and corrosion resistance. After solution and aging treatment, it has the same high strength limit, elastic limit, yield limit and fatigue limit as special steel, but also has high electrical conductivity, thermal conductivity, high hardness and wear resistance, high creep resistance and corrosion resistance. Beryllium copper is widely used in the manufacture of various mold inserts, replacing steel to make molds with high precision and complex shapes, welding electrode materials, die casting machines, injection molding machine punches, wear and corrosion resistance work. Beryllium copper strip is used in micromotor brushes, mobile phones, batteries, products, and is an indispensable industrial material for national economic construction. 2 Beryllium cobalt copper Beryllium cobalt copper has excellent corrosion resistance, excellent polishing, excellent wear resistance, excellent adhesion resistance, high strength and high hardness, extremely excellent weldability. Beryllium cobalt copper and its excellent thermal conductivity is about 3 to 4 times better than mold steel. This feature ensures rapid and uniform cooling of plastic products, reduces deformation of products, unclear shape details and similar defects, and can significantly shorten the production cycle of products in most cases. Beryllium cobalt copper is widely used in the manufacture of inserts and die cores in injection molds or steel molds. When used as an insert in plastic molds, it can effectively reduce the temperature of the heat concentration area and simplify or eliminate the cooling channel design. The existing factory specifications of beryllium cobalt copper include: forged and rolled round and flat, extruded tubes, machined mandrel, ingots and various cast profiles. 3 Beryllium bronze Beryllium bronze A tin-free bronze with beryllium as the main alloy component, containing 1.7 to 2.0% beryllium and a small amount of nickel, chromium, titanium and other elements. After quenching aging treatment, the strength limit can reach 1250~1500MPa, which is close to the level of medium strength steel. In the quenching state plasticity is very good, can be processed into a variety of semi-finished products. The main characteristics of beryllium bronze are: high hardness, good elasticity, wear resistance, but also has good corrosion resistance, thermal and electrical conductivity, and does not produce sparks when impacted. Widely used as an important elastic component, wear-resistant parts and explosion-proof tools. Commonly used brands are QBe2, QBe1.7, QBe1.9 and so on. |
