Meta-Braze™ 4775
Meta-Braze™ 4775 can be specified for high strength, heat resistant joints. Used in highly stressed jet engine components. As a braze alloy it defuses well into parent metals.
Nickel Based Brazing Alloys
New Nickel Products
We can supply nickel brazes in novel new forms such as flexible rope and solid wire.
Product Uses and Applications
Nickel brazing products are used extensively in aerospace, automotive and nuclear industries. In these applications they would typically be used to join stainless steel and high temperature superalloys. VBC Group manufactures aerospace grade nickel braze paste and stocks many grades of nickel braze powder for these industries. In addition, VBC Group can supply nickel braze foil and preformed shapes.
