Good Performance Nichrome/ Nickel based Alloy Bright Flat Strip/ Ribbon
Nickel based alloys are used in those applications that require enhanced properties when compared to stainless steel. As a superior product to stainless, these alloys are reserved for the most demanding of environments from extremely high temperatures to the most corrosive of atmospheres. We have the equipment, knowledge, imagination and technology to allow them to deliver on the most demanding specifications.
For the past five years we have gained a highly enviable reputation for our knowledge in these areas and are now one of the leading UK suppliers of nickel based alloy strip, all produced to customer specification and so understanding our customers requirements is central to our philosophy.
