KUPROY® 4 is a high-performance, precipitation-hardened copper alloy that offers an excellent balance of electrical conductivity and mechanical strength. By alloying copper with Nickel and Silicon, this material provides superior resistance to wear and thermal stress. It is a preferred engineering solution for components that require high reliability under both electrical and mechanical loads.

CuBe2 is the strongest of all copper-based alloys, offering mechanical properties comparable to many high-strength steels but with the added benefits of copper’s thermal and electrical conductivity. Often referred to as "The Master Alloy," it achieves its peak performance through precipitation hardening, resulting in extraordinary hardness, fatigue resistance, and durability.

Developed by Çorum Bronz, KUPROY 1 (CuCrZr) is a specially alloyed resistance welding copper that combines maximum electrical and thermal conductivity with high mechanical hardness. It provides superior heat transfer and erosion resistance in resistance welding (spot welding) electrodes, plastic injection molds, and heavy-duty electrical contacts.

KUPROY® 2 is a high-performance copper alloy that bridges the gap between high conductivity and extreme mechanical strength. By alloying copper with Cobalt and Beryllium, this material achieves exceptional hardness and thermal stability through precipitation hardening. It is the premier choice for applications where high thermal conductivity must be paired with resistance to mechanical wear and high temperatures.

KUPROY  (Cu-ETP) is a high-purity electrolytic tough pitch copper characterized by its exceptional electrical and thermal conductivity. With a minimum copper content of 99.90%, it is the primary material for electrical engineering and power transmission. It offers excellent formability and solderability, making it the industry standard for high-efficiency conductive components.
