Copper is a popularly used ductile metal. Some of the properties are: malleable, ductile, good conductor of heat, good conductor of electricity-in pure state, and also finds extensive use as a thermal and electrical conductor, as a building material, and as an important component of various alloys. Some of the widely used alloys are bronze, brass and monel/ cupronickel, which are also important alloys for Nexteck Technology Limited.

Casted copper alloys have high tensile and compressive strength, have good wear qualities when subjected to metal-to-metal contact, are easily machined, have good thermal and electrical conductivity, and high corrosion resistance for maximizing product performance.

Copper casting can be used to produce parts in shapes that cannot be easily attained with fabrication techniques, such as - forming or machining. The composition of copper casting alloys may differ from those of their wrought counterparts for a variety of reasons. Usually casting allows greater latitude in the application of alloying elements, because the effects of composition on cold or hot working properties are not significant.

Copper alloy castings are applicable to occasions requiring superior corrosion resistance, high electrical or thermal conductivity, superior bearing-surface qualities or some other special properties. Some of the common examples include bearings, bushings, gears, fittings, valve bodies, and miscellaneous components for chemical processing applications.
