DHT Alloys: New Self-Lubricating, Wear and Gall Resistant, High-Strength Aluminum Alloys 2001-01-0410
In 1989 a major development program was initiated to engineer an aluminum silicon alloy to address unique manufacturing, functional requirements and environmental concerns. The result was the family of patented DHT alloys. The DHT alloys are self-lubricating, wear and gall resistant, high strength aluminum alloys. This paper highlights unique properties of these engineered alloys and applications that can take advantage of the beneficial features of these alloys.
Detail mechanical and physical property data will be presented (Tables 1&5). Also, photos of microstructures and cast components will be presented. A new breed of engineered alloys designed with due consideration to foundry, manufacturing and functional requirements have been developed and commercialized.
