We offer Copper Chromium Zirconium CuCrZr: C18150, C18200 for spot welding.

C18150 Chromium Zirconium Copper. 
CuCr1Zr – UNS.C18150 Chromium Zirconium Copper C18150 is an excellent and unique copper alloy with high electrical conductivity, hardness, and ductility, moderate strength, and excellent resistance to softening at elevated temperatures. The addition of 0.1% zirconium (Zr) and 1.0% chromium (Cr) to copper results in a heat treatable alloy which may be solution treated and subsequently aged to produce these desirable properties. Rod is usually supplied from the mill in the fully aged and drawn condition so no further heat treatment is required by the fabricator. The softening temperature of properly heat treated C18150 rod exceeds 500°C as compared to unalloyed pure copper which softens at 200°C, and silver bearing coppers which soften at 350°C.

We offer Beryllium Copper Rods in Grades C17200,C17300,C17500 & C17510 for differnt applications.Beryllium copper (C17200 & C17300) is an age-hardening alloy which attains the highest strength of any copper base alloy. It may be age hardened after forming into springs, intricate forms or complex shapes. It is valued for spring properties, corrosion resistance, stability, conductivity, and low creep.

Tempered beryllium copper is C17200 & C17300 that has been age hardened and cold drawn. No further heat treatment is necessary beyond a possible light stress relief. It is sufficiently ductile to wind on its own diameter and can be formed into springs and most shapes. Tempered wire is most useful where the properties of beryllium copper are desired, but age hardening of finished parts is not practical.

C17510 and C17500 beryllium copper alloys are age-hardenable and provide good electrical conductivity, physical properties, and endurance. They are used in springs and wire where electrical conduction or retention of properties at elevated temperatures is important.

High strength beryllium copper alloys contain as much as 2.7% beryllium (cast), or 1.6-2% beryllium with about 0.3% cobalt (wrought). The strength is achieved by age hardening. The thermal conductivity of these alloys lies between steels and aluminium. The cast alloys are frequently formed with injection molds. The wrought alloys are designated by UNS as C17200 to C17400, the cast alloys are C82000 to C82800. The hardening process requires rapid cooling of the annealed metal, resulting in a solid state solution of beryllium in copper, which is then kept at 200-460 °C for at least an hour, producing a precipitation of metastable beryllide crystals in the copper matrix. Overaging beyond the equilibrium phase depletes the beryllide crystals and reduces the strength. The beryllides in cast alloys are similar to those in wrought alloys.

High conductivity beryllium copper alloys contain as much as 0.7% beryllium with some nickel and cobalt. The thermal conductivity of these alloys is greater than aluminium and slightly less than pure copper and are often used as electrical contacts.^[4]

We offer Be Windows for X Rays Tubes:
Additional to the numerous quality tests during production, we carry out repeated functional tests at high-voltage for each individual X-ray tube. In spite of all the experience, the manufacture of an X-ray tube remains a complex and high-risk process. That is why the substantial effort involved for all the fail-safe testing is an investment well made.
We offer Center Beryllium Tubes & Side Beryllium Tubes
