Alloy Wire inspect all phases of production and our test equipment can verify the tolerance of the wire/tape/ribbon/section/profile, surface quality, roundness, strength properties and the stress required to breaking point.
Please see our standard tolerances below.
We can offer tighter tolerances, please let us know what tolerance you require.
