Copper-nickel alloys 79HM, 36NHTYu, Monel, 29HK available and under the order from a warehouse in Dnipropetrovsk, delivery


Copper alloys with nickel differ in good mechanical properties, corrosion resistance, technological effectiveness and special electric characteristics that causes broad application them in equipment.

Copper forms continuous solid solutions with nickel. Nickel significantly strengthens copper, and alloys of approximately ekviatomny structure have the maximum durability and hardness. It is important to note that at the same time characteristics of plasticity and impact strength practically do not change. Nickel raises characteristics of thermal stability, the module of elasticity and lowers temperature coefficient of resistance of copper.

To destination copper-nickel alloys are divided into two groups: constructional ielektrotekhnichesky. To the first group high-strength and corrosion-resistant alloys like cupronickel, a German silver and kunial, concern to the second — a constantan, manganin and a thaw, having the high electric resistance and certain thermoelectric properties.
