Cast-iron parts with little machining do not prove any saving. the handicap on the cost of material is too great to overcome to make an attractive showing. Generally speaking. intricate parts made in brass and used in large quantities yield the greatest saving. However. circumstances and individual cases differ so much that no general rule can be outlined and. therefore. we gladly give our advice on any part at any time. or enter into correspondence on all subjects relating to die-casting with parties interested or seeking information. The following is a brief attempt to give the main characteristics of our different alloys and their usefulness. No. 3 Metal. Zinc. alloy hard. good bearing metal. compares favorably with cast iron. Can be plated any color. No. 47 Metal. Tin alloy. Good bearing metal. medium priced. Toughness of soft brass. Noncorrosive. No. 28 Metal. Tin alloy. Genuine babbitt found after many years of actual service to be best suited for light gas engine work. No. 51 Metal. Lead alloy: acid proof metal. Used for machine parts where a non-corrosive metal is required and where working strain is low. No. 12 Metal. Aluminum alloy: consisting of aluminum and copper. High tensile strength. tough and durable. Takes and holds high polish. This alloy conforms with the Aluminum Company's standard No. 12 alloy. Vulcanized Fibre AMERICAN VULCANIZED FIBRE CO. Established" 1873 WILMINGTON, DELAWARE VULCANIZED FIBRE Manufacture--In the manufacture of fibre there are three factors absolutely essential to mechanical strength and electrical insulation: 1. Pure Raw Material. 2. Experience and care in the process of making. 3. Freedom from chemicals ...
