Material Notes:
Isostatically molded ATJ has been an industry standard for many years. It is a fine grain, high strength material which can be machined to precise tolerances and a fine surface finish. Grade ATJ has unique thermal shock resistance due to the combination of low thermal expansion, high thermal conductivity and low elastic modulus.Typical Applications:Permanent molds Composite tooling Mandrels Continuous casting dies Hot pressing molds and punches Rocket motor nozzles Plungers and ramsTabular property data is typical.
