PRECISION BAR

We supply stainless steels, titanium, titanium alloys and nickel base alloys with tight tolerances from the Zapp-group. In-line grinding, polishing, crack detection, cutting and chamfering are only a few of the advantages with precision bars from Zapp. Materials with highly strict demands on homogenous magnetic properties such as for magnetic valves and metals for medical implants are only two examples where material from Zapp is used. Ultra sonic testing can be offered on request.
