  Zinc also is used to produce die-casting alloys, and it is often alloyed with lead and tin to make solder, which has a low melting point and is used to join electrical components and pipes. Like lead-free pewter alloys, lead-free zinc alloys are useful for many types of .   In the CASS testing of outside door handles plated in one of six exterior die-cast plating machines equipped for the dual chromium system at the Flint, Michigan plant of the Ternstedt Division of General Motors Corporation, 97% of the handles tested presented an appearance which it is felt would be acceptable to a car owner after one year's service.
