New nickel coated wire launched

Sandvik Coromant UK : 25 May, 2000  (Company News)
Sandvik Steel has launched a new nickel coated spring wire, designated gusab Nicoat 'A'.
The new wire has been specially developed and is aimed particularly at the spring wire and electronic industries in the US and Europe where it is expected to be very competitive.

Nickel coated wire offers advantages in high speed coiling and gives a better yield in the production of springs compared to non nickel coated wire. Its key benefits are easier and more even coiling, less wear on coiling tooling, tempering without degreasing or discoloration and good soldering properties.

Gusab Nicoat 'A' is available with a coated or alternatively a bright surface finish.

The coated surface consists of a lubrication layer which is made up of mainly sodium and calcium compounds and is almost free from chlorides. Designed to provide high output in the production of springs including those requiring close gauge and spring force tolerances, no additional lubrication is needed to achieve high feed rates.

There is also less possibility of the wire surface being scratched during coiling which minimises the risk of fatigue failure. Any coating remaining on the finished spring can be removed using alkaline agents.

Bright drawn wire has its surface covered with a very thin oil film. Lubricant is needed only when coiling springs with a complex design.

Coated wire is available in a size range from 0.22 up to 2.50 mm diameter and 0.15 to 0.80 mm for bright finish.
