Following the successful introduction of K-Alloy in 2003, Delphi Corp., Troy, Mich., has added another aluminum alloy formula to its portfolio. The new alloy -- K-Alloy SP -- can be used in sand casting and permanent mold applications while maintaining a high-corrosion resistance at a lower cost compared to other alloys.
“The original K-Alloy continues to provide aluminum die casting with exceptional corrosion
resistance results in vehicle engine electronics, sporting goods, outdoor lighting, furniture and mail
boxes, just to name a few. But K-Alloy SP allows us to work with an expanded set of users that
utilize permanent molds and sand casting in their process,” said Timothy Forbes, director, Delphi
Technologies, Inc. (DTI), a wholly owned subsidiary of Delphi that is responsible for licensing and
commercializing products such as K-Alloy SP.
Delphi’s K-Alloy SP has the same benefits as the original K-Alloy in that it resists corrosion
and can eliminate costly processes designed to slow corrosion including anodizing, chromating,
powder coating and painting. Because it was originally developed for use within the automotive
industry, it can withstand extreme salt corrosion and temperatures, vibration and shock. It has
been tested to withstand 3,000 hours of salt spray testing exceeding the performance of other
commercially available alloys.
Delphi has licensed Beck Aluminum to produce and market K-Alloy SP in addition to the
original K-Alloy. The agreement allows interested companies a simplified process to gain access to
the patented material. Delphi has also expanded its global availability through a recently
established agreement with a smelter in China.
Additionally, as a result of experience with the alloy and process refinement, Beck is now
able to provide a more competitive price for K-Alloy and K-Alloy SP.
Delphi Corp. is a global supplier of electronics and technologies for autos,
commercial and other vehicles. For more information on Delphi, visit www.delphi.com.
