KUPROY® 2: CuCo2Be – The Power of Precision and Durability

In high-speed production environments, thermal fatigue is the leading cause of component failure. KUPROY® 2 (CuCo2Be), manufactured with the advanced metallurgical expertise of Çorum Bronz, is specifically engineered to solve this. As a premium Cobalt Beryllium Copper alloy, it offers a unique combination of high electrical and thermal conductivity with a level of hardness typically found in high-strength steels.

The Technical Advantage

The secret to KUPROY® 2’s success lies in its response to heat treatment. Unlike pure copper, which softens under heat, KUPROY® 2 undergoes a precipitation hardening process that locks its crystalline structure, allowing it to maintain its yield strength and hardness at temperatures where other alloys would deform.

  • Enhanced Productivity: In plastic molding, KUPROY® 2’s high thermal conductivity reduces cooling times by up to 20-30%, directly increasing your parts-per-hour output.

  • Non-Sparking Safety: Its high-strength, non-sparking nature makes it vital for tools and components used in explosive or hazardous environments.

  • Longevity: Superior resistance to "mushrooming" and wear means your welding electrodes and plunger tips last significantly longer, lowering your total cost of ownership.

Çorum Bronz provides KUPROY® 2 in a variety of forms, including round bars, plates, and custom-forged blocks, all produced in compliance with international standards such as DIN 2.1285 and RWMA Class 3.
