Product Description
Ohmalloy Material Co.,Ltd is the leader company in the manufacture of beryllium-copper alloys. We actively participate in all environmental studies made on all substances used in our products. Our priority is to comply with all legal regulations in force to ensure the continued existence of our products to our clients.
Beryllium-Copper-alloys are mainly based on copper with a beryllium addition. High strength beryllium copper alloys contain 0.4-2% of beryllium with about 0.3 to 2.7% of other alloying elements such as nickel, cobalt, iron or Lead. The high mechanical strength is achieved by precipitation hardening or age hardening.
It is the best high-elastic material in copper alloy. It has high strength, elasticity, hardness, fatigue strength, low elastic hysteresis, corrosion resistance, wear resistance, cold resistance, high conductivity, no magnetism, no impact, no sparks, etc. A range of excellent physical, chemical and mechanical properties.
Properties
The best combination of characteristics of the copper-based alloy
The copper-beryllium alloys have a wide combination of mechanical and electrical properties which is unique for copper alloys. The mechanical strength achieved after heat treatment ranks highest amongst all the copper alloy materials and is combined with a high electrical conductivity which outperforms that of bronzes. T
High Strength & Elastic Modulus
Beryllium Copper alloys can achieve very high mechanical properties after heat treatment, up to 1500 Mpa in tensile strength and hardness as high as 450 Vickers.
The strength of these alloys allow for the design of smaller, lighter components that can endure high bending stresses when used as springs material.
Bending Formability
Beryllium Copper can be formed into complicated shapes in an annealed or cold-worked temper.
The highest mechanical properties can be achieved with proper heat-treatment after forming.
High Fatigue Strength
Beryllium Copper exhibits excellent resistance to fatigue under reverse bending (up to 300 MPa) which qualifies its use in applications where other alloy fail to provide the same level of reliability.
High Electrical conductivity
Beryllium Copper exhibit a high electrical conductivity ranges from 22 to 70% IACS depending on the alloys and temper. Beryllium Copper is often used as high current density spring material.
Application
Our alloys combine a range of properties particularly suited to meet the exacting requirements of many applications in the automotive, electronic, aeronautical, Oil&Gas, watch, electro-chemical industries, etc. Beryllium Copper is widely used in those fields as contact springs in various applications like connectors, switches, relays, etc
