Delphi K-Alloy A304 Casting Alloy
Categories: Metal; Nonferrous Metal; Aluminum Alloy; Aluminum Casting Alloy

Material Notes: Delphi's K-Alloy/A304 is a patented casting alloy engineered to protect today's most critical components from harsh operating environments. It also has high elongation properties when compared to other aluminum die casting alloys.


  • Excellent corrosion resistance offers unique engineering solutions
  • High elongation properties
  • Superior finishing quality for high polish applications
  • Better thermal conductivity for improved cooling (15% over A380)
  • Eliminates pre and post processing needs such as anodizing and paint
  • Same castability and flow properties as standard die cast alloys
  • Same shrink factors as existing molds
  • Die life similar to A380
  • No special tooling or process parameters required
Typical Applications
  • Electronic component housings exposed to harsh environments
  • Indoor and outdoor lighting, such as LED lighting
  • Automotive structural components
  • Recreational equipment, such as boats and fishing equipment
  • Defense applications, such as drones, military radios, and antennas
  • Automotive, transportation, and harsh under hood environments
