Bezinal® XP coated wire for reliable, superior corrosion resistant springs
Bezinal® XP is a new type of zinc aluminum coated wire that has been specifically designed for spring applications used in highly humid or alkaline environments (e.g. automotive springs, industrial springs, etc.). Its advanced properties offer superior corrosion resistance without requiring additional post-coating.
Benefits:
- superior corrosion resistance;
- excellent cathodic protection at grinded and cut edges;
- improved white rust protection;
- retains properties even after exposure to stress-relieving temperatures;
- economic alternative to specific stainless steel spring applications.
Several corrosion tests like salt spray, Kesternich, humidity and outdoor exposure tests, have demonstrated that Bezinal® XP not only offers the best protection in its range but also outperforms traditional zinc coatings.
Moreover, this coating maintains this property even after heavy deformation and heat exposure, eliminating the need for complex, expensive and environmentally unfriendly post-coating processes.
