Nickel, Aluminum, Bronze Conversion Chips to C95800 Alloy Ingots

1. The material to be smelted is machine chips/turnings of Nickel, Aluminum, Bronze, Copper Alloy C95800 contained within water soluble machining coolant. 2. The collected metal shall be processed into 42-inch diameter ingots weighing 4,500 to 5,500 pounds each, or 24 inch diameter ingots weighing approximately 2,500 pounds each. The contractor is to contact Bruce Bucari, NFPC Foundry Materials Engineer to provide the ingots size for each batch. Bruce Bucari can be contacted at 215-897-3256. The ingots shall meet the following criteria:Element PercentAluminum 8.8 - 9.2Manganese 1.1 - 1.5*Nickel 4.0 - 5.0*Iron 3.5 - 4.2Silicon 0.05 MaximumLead 0.01 MaximumCopper (Plus Other 99.7 Minimumspecified Elements)3. Each 42 inch diameter ingot is to have two (2) lifting hooks. The hooks are to be made from one (1) inch diameter mild steel rod. The hook opening is to be three (3) inches wide and clear the top of the ingot by a minimum of six (6) inches. These hooks shall be far enough apart to allow another ingot to be stacked upon the first between the hooks. 4. Each 24 inch diameter ingot is to have two (2) lifting hooks as detailed for the 42 inch diameter ingot in paragraph three above but shall be made from the same alloy. 5. Ingots shall be palletized, marked with the lot number and ingot weight, and shipped in an open flatbed trailer to facilitate unloading by bridge crane or fork truck. Seven (7) small ingots shall be poured matching and supplied with each 42 or 24 inch ingot. 6. The contractor shall provide a chemical analysis for each ingot. The mechanical properties, tensile strength 0.5% extension under load yield strength, and elongation are to be determined and provided for each lot with the following criteria:Tensile Strength 85 KSI minimumYield strength 35 KSI minimumElongation 15% minimum7. The steps required by the contractor to collect the non-ferrous smelter are as follows: (a) Provide sufficient collection bins and collection frequency for a chip output of approximately 20,000 pounds per month (Approximately 20 cubic yards) (b) Contents of bins will be Nickel, Aluminum, Bronze, Copper Alloy C95800. (c) Clean (chips will be contaminated with a water soluble machining coolant) and smelt the bin contents in acccordance with the re-melt specification provided.(d) Return/deliver the processed ingots to the customer as the material is collected and processed. (e) Maintain and deliver to the customer, on a monthly basis, an accurate record of both processed and delivered poundage. 8. A report indicating the results of chemical and mechanical testing is to be sent to the Naval Foundry and Propeller Center:
