I search for Nichrome plate long time, and successfully bought it from Ohmalloy material. OHMALLOY provide real good service in alloy service and can always help me in finding the correct resistance alloy.

—— Mike Harness

OHMALLOY can provie me only 1kg Kovar alloy wire 1.0mm with short time, that is really amazing. Thanks

—— Janey

Really professional in thermocouple wire and cable, what i want just can get from OHMALLOY

—— Chris

Enamelled Constantan 0.08mm, i never expect to get only 2kg of it. But OHMALLOY supply it to me with good quality. God Jesus! Such a reliable supplier from china

Annealling State Hardness<130HV 0.25mmx250mm C17200 Beryllium Copper Strip

   

     Ohmalloy Material Co.,Ltd is the leader 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.

HTB1WsbycuuSBuNjSsplq6ze8pXa9.jpg    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.

 

Heat treatment

    Heat treatment is the most important process for this alloy system. While all copper alloys are hardenable by cold working, beryllium copper is unique in being hardenable by a simple low temperature thermal treatment. It involves two basic steps. The first is called solution annealing and the second, precipitation or age hardening.

Solution Annealing

    For the typical alloy CuBe1.9 (1.8- 2%) the alloy is heated between 720°C and 860°C. At this point the contained beryllium is essentially “dissolved” in the copper matrix (alpha phase). By rapidly quenching to room temperature this solid solution structure is retained. The material at this stage is very soft and ductile and can be readily cold worked by drawing, forming rolling, or cold heading. The solution annealing operation is part of the process at the mill and is not typically used by the customer. Temperature, time at temperature, quench rate, grain size, and hardness are all very critical parameters and are tightly controlled by ohmalloy.

Age Hardening

    Age hardening significantly enhances the material’s strength. This reaction is generally carried out at temperatures between 260°C and 540°C depending on alloy and desired characteristics. This cycle causes the dissolved beryllium to precipitate as a beryllium rich (gamma) phase in the matrix and at the grain boundaries. It is the formation of this precipitate which causes the large increase in material strength. The level of mechanical properties attained is determined by the temperature and time at temperature. It should be recognized that beryllium copper has no room temperature aging characteristics.

 

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
