Ti-6Al-2Sn-4Zr-2Mo - 3.7144 Titan circle, rod, sheet

Ti-6Al-2Sn-4Zr-2Mo - 3.7144 Titan circle, rod, sheet

Supplier — AvekGlob company offers to buy at affordable prices from the manufacturer a sheet, bar and circle, which are made of Ti-6Al-2Sn-4Zr-2Mo titanium alloy (alloy 3.7144). The supplier guarantees the prompt delivery of rolled metal to any address specified by the customer.

Technical specifications

Ti-6Al-2Sn-4Zr-2Mo (alloy 3.7144) is a pseudo alpha-alloy of titanium, since it contains a small amount of plastic beta phase. This alloy was developed for high-temperature operation conditions at temperatures reaching 538 ° C. The alloy has a combination of excellent strength and corrosion resistance with relatively good welding ability, as well as manufacturability in machining and plastic deformation. The presence of silicon increases the alloy’s resistance to high-temperature creep.

Urgency of application

A sheet, bar or circle made of Ti-6Al-2Sn-4Zr-2Mo titanium pseudo alloy (alloy 3.7144) is used for the production of various products in the aerospace and automotive industries. Typical details are high-temperature jet engines, components of gas turbine compressor units (vanes, disks, spacers and seals), as well as temperature-resistant automobile valves, sheet metal parts in afterburners and sections of operating aircraft engines.
