Innovation Tesla Submits Patent Application for New Aluminum Alloys
Apparently Tesla has developed a new aluminium alloy for die casting of car parts, which besides a high yield strength can also maintain a high conductivity - this is supported by a new patent application submitted by the car manufacturer.
As Electrek reports, the Tesla materials team led by alloy expert Charles Kuehmann has developed new aluminum alloys for die casting. A patent application of the car manufacturer also speaks in favour of this. An extract from the patent reads as follows:
„It may be desirable to produce cast aluminum alloys with high yield strength such that the alloys do not fail easily while also containing sufficient conductivity for various applications. The aluminum alloys may be used in defferent automotive parts, including rotors, stators, busbars, inverters, and other parts. Current cast alloys do not well serve these parts the application of the parts. There still remains a need to develop cast aluminum alloys with high strength, improved conductivity, and sufficient castability.“
A summary of the disclosure also reveals the following:
„The disclosed aluminum alloys are aluminum alloys with high yield strength, high extrusion speed, and/or high thermal conductivity. In certain variations, the alloys are pres quenchable, allowing processing without additional subsequent solution heat treatment while not compromising the ability to form an aluminum alloy having a high yield strength as described herein. The aluminum alloys are designed for use with casting techniques. Die casting is preferentially used, altough sand casting (green sand and dry sand), permanent mold casting, plaster casting, investment casting, continuous, or another casting type may be used.“
