BS2874: NS101: BS2870: NS104 / NS106 - Silver Speed - XL
We deal in offering our clients a wide range of Nickel Silver Rod that is manufactured using the high-grade material. Nickel Silver is a copper alloy with additions of zinc and nickel. Their special blend of mechanical properties, physical properties and performance characteristics depend upon the relative proportions of the three elements. Their attractive color varies from pale gold to silvery white. These copper alloys are termed nickel silver because they contain nickel and are, by and large, silvery in appearance. But the term is somewhat misleading since they are neither nickel-based nor do they contain silver! They are best considered as brasses to which nickel is added, primarily to improve tarnish resistance, oxidation resistance, and general mechanical performance characteristics.
Nickel Silvers are capable of providing a unique combination of strength, high modulus spring properties, corrosion and oxidation resistance, anti-galling properties, excellent cryogenic performance and numerous other attributes combined with ease of forming, machining plating and joining.
Silver speed-XL Extra Free-Machining Rod:
This is a free-machining alloy with a machineability almost the same as free-cutting brass. It is highly recommended for the production of intricate components by complex machining operations. This grade is stocked exclusively by Columbia and as with all standard grades, will be specified in the new European Standards for copper based alloys. It has basically the same application and performance characteristics as NS101, but with an invaluable increase of around 20% in machineability.
