Lithium copper pieces eliminate porosity, improve casting conductivity. (Case History).West Coast Stainless Products, a custom caster located in Huntington Park, California Huntington Park is a city in Los Angeles County, California, United States. As of the 2000 census, the city had a total population of 61,348. History Named for prominent industrialist Henry Huntington, Huntington Park was incorporated in 1906 as a streetcar suburb for , relies on lithium to degas Degas To release and vent gases. New building materials often give off gases and odors and the air should be well circulated to remove them. Mentioned in: Multiple Chemical Sensitivity its molten baths. Founded in 1970, the 46-employee foundry primarily serves the pump industry, but it also produces 50 different alloys for custom castings from 1-4500 lb. In the past, lithium has been supplied in copper cartridge form. Due to concerns about handling pure lithium, the firm has had to deal with restrictions on shipping. In addition, moisture may infiltrate the cartridge, resulting in an explosive reaction when the cartridge is introduced to the molten metal. Today, West Coast Stainless Steel stainless steel: see steel. stainless steel Any of a family of alloy steels usually containing 10–30% chromium. The presence of chromium, together with low carbon content, gives remarkable resistance to corrosion and heat. is using 2% lithium copper alloy pieces provided by Belmont Metals, Inc., Brooklyn, New York New York, state, United States New York, Middle Atlantic state of the United States. It is bordered by Vermont, Massachusetts, Connecticut, and the Atlantic Ocean (E), New Jersey and Pennsylvania (S), Lakes Erie and Ontario and the Canadian province of . The lithium copper pieces come cleaned and polished, which removes the surface oxides that often can cause defects in fine-detailed castings. Two-percent lithium copper also is an ideal deoxidizer de·ox·i·dize tr.v. de·ox·i·dized, de·ox·i·diz·ing, de·ox·i·diz·es To remove oxygen from (a compound); reduce. de·ox for pure copper, copper-base alloys and precious metals. It helps eliminate gas holes, porosity and metal oxides while increasing fluidity, resulting in more successful castings. Unlike other deoxidizers such as phosphorus copper, lithium copper allows the foundry to make pure copper castings with close to 100% conductivity (as opposed to the 30% or less conductivity that can result when using other deoxidizers). According to West Coast Stainless CEO (1) (Chief Executive Officer) The highest individual in command of an organization. Typically the president of the company, the CEO reports to the Chairman of the Board. Charles Elrod, the product is "easy to store as well as ship." In addition, he said that the alloy pieces allow for pouring a clean heat of metal. Circle No. 003 on last page. |
