Beryllium Copper Round Bar Supplier & Stockist in India

HOME → Hot Products → Beryllium Copper → Beryllium Copper Round Bar

Beryllium copper round bar is a copper-based alloy available in grades such as C17200 and C17500, combining high strength, hardness, electrical conductivity and resistance to wear. C17200, also known as CuBe2 or Alloy 25, is commonly supplied in annealed, cold worked and precipitation-hardened conditions for applications requiring higher mechanical strength. C17500 is selected where a balance of strength and electrical or thermal conductivity is required.

These beryllium copper bars are available in standard and custom diameters, with options for different tempers, surface finishes and cut lengths. They are used for electrical contacts, springs, mould components, welding equipment, precision tooling, connectors and components exposed to repeated mechanical loading. Beryllium copper rod is another common product term for the same round bar form.

Sachin Steel Centre supplies and stocks beryllium copper round bars in C17200 and C17500 for industrial and engineering requirements. If you also need other forms, see our Beryllium Copper Wire and Beryllium Copper Sheet pages, or browse the full Beryllium Copper range.

Frequently Asked Questions

FAQ – Beryllium Copper Round Bar

What is beryllium copper round bar and what is it used for?

It is a high-strength, precipitation-hardening copper alloy bar used for welding electrodes, bearings, bushings, springs, mould inserts and non-sparking tools.

C17200 vs. C17500: which should I choose?

Choose C17200 when strength is the priority. Choose C17500 when you need about 50% IACS conductivity with moderate strength.

What do the tempers TB00, TD04, TF00 and TH04 mean?

TB00 is solution-annealed (soft), TD04 is cold-worked hard, TF00 is solution-annealed and aged, and TH04 is hard and aged for full strength.

Which standard applies ASTM B196 or B441?

ASTM B196 covers C17000, C17200 and C17300 rod and bar. ASTM B441 covers C17500 and C17510.

What diameters and lengths are available?

Round bar from 3 mm to 800 mm diameter, in lengths of 1000 mm to 6,000 mm. Other sizes on request.

Is beryllium copper safe to machine?

Solid bar is routinely handled, but machining, grinding or welding can create beryllium dust or fume. Use extraction and follow local exposure rules.

Is beryllium copper magnetic or non-sparking?

It is non-magnetic and non-sparking, which is why it is used in hazardous areas and around sensitive instruments.

Do you provide test certificates, and what affects price?

Yes, a mill test certificate to EN 10204 3.1 comes with every order. Price depends on grade, diameter, temper, length and quantity.
