World's strongest aluminum alloy
A new patent-pending aluminum alloy from Kobe Steel is made using a spray forming process and is said to be the strongest aluminum alloy available. It has a tensile strength of 780 MPa. That's reportedly 10% higher than the 710 MPa of Weldalite, an aluminum-lithium alloy developed by and used

Aluminum
Though light in weight, commercially pure aluminum has a tensile strength of about 13,000 psi. Cold working the metal approximately doubles its strength. In other attempts to increase strength, aluminum is alloyed with elements such as manganese, silicon, copper, magnesium, or zinc. The alloys can

Cost-conscious molding
Permanent graphite molds and a knowledgeable metal-casting house can help designers of zinc-aluminum-alloy parts go from art to part in less than six weeks. Edited by Jean M. Hoffman Most ZA-12 (zinc-aluminum) alloy parts need little or no secondary machining. However, when necessary, a shop

Alloy coating extends bearing life in harsh environments
A thin zinc-alloy coating that can be applied to production bearings lets them tolerate wet environments and extend bearing life. The coating, called AquaSpexx, is a product specification engineered to increase performance of Timken bearings in applications subject to water-based corrosion damage
