Titanium Braze 590
TiBraze-590 is a corrosion resistant filler metal suitable for brazing titanium, niobium, refractory metals, aluminides and stainless steels. It can also be used to join ceramics, graphite and carbon composites to metals and other non-metallic components without the need for prior metallization of the contact surface. Joints brazed with TiBraze-590 can be used in service temperatures up to 1022°F (550°C) for long term exposure.
Available Forms
Amorphous foil and specialty preforms per customer specifications
Characteristics
Suitable for use in all vacuum brazing applications as well as under partial pressure of argon gas. Brazing of alloys containing active components under protective nitrogen atmosphere is not recommended. It is important to maintain a high purity, oxygen-free environment; any oxidation of reactive elements will limit alloy wettability across the non-metallic surface. A vacuum of 10-4 torr or better is required to successfully braze with TiBraze-590. For controlled atmosphere brazing or vacuum brazing the recommended radial joint clearance for active alloys ranges between 0-0.002 in (0-0.05 mm).
Properties
The properties of a brazed joint are dependent upon the base metal, joint design and brazing technique. Below are several examples of shear strengths recorded for joints brazed wit TiBraze-590: Base Metal Titanium Grade 2 Ti-6Al-4V Titanium to Stainless Titanium to Copper Titanium to Nickel-lated Steel Shear Strength Titanium Grade 2: 200-235 MPa Ti-6Al-4V: 180-207 MPa Titanium to Stainless: 62-97 MPa Titanium to Copper: 83-110 MPa Titanium to Nickel-plated Steel: 95-124 MPa
