Beryllium copper is a susaturated 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, beryllium copper has the same high strength limit, elastic limit, yield limit and fatigue limit as special steel. At the same time, it also has high electrical conductivity, thermal conductivity, high hardness and wear resistance. High creep resistance and corrosion resistance, widely used in the manufacture of all kinds of mold inserts, instead of steel production of high precision, complex shape of the mold, welding electrode materials, die casting machine, injection molding machine punch, 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.

Parameters: Density 8.3g/cm3 Hardness before quenching 200-250HV Hardness after quenching ≥36-42HRC Quenching temperature 315℃≈600℉ quenching time 2 hours

Softening temperature 930℃ Hardness after softening 135±35HV Tensile strength ≥1000mPa Yield strength (0.2%) MPa: 1035 Elastic modulus (GPa) : 128 conductivity ≥18%IACS thermal conductivity ≥105w/m.k20℃

Beryllium copper is divided into high beryllium copper and low beryllium copper. High beryllium copper refers to beryllium copper containing more than 2.0 beryllium. Beryllium copper belongs to the resistance welding electrode material for welding, good electrical and thermal conductivity, high hardness. When welding, the electrode loss is less, the speed is fast, and the cost is low.
1. Brand: C17200
2. Softening temperature: 930ºC

Beryllium copper is a copper alloy with beryllium as the main alloying element, also known as beryllium bronze. It is the best performance of advanced elastic materials in copper alloys, with high strength, elasticity, hardness, fatigue strength, low elastic hysteresis, corrosion resistance, wear resistance, cold resistance, high conductivity, non-magnetic, impact does not produce sparks and a series of excellent physical, chemical and mechanical properties. Beryllium copper color, generally will show red or yellow two colors, beryllium copper color yellow and red are normal, because in the production and storage process there is a chemical reaction of oxidation, is the color change.
