Detailed Description

C18000 Details & Applications: C18000 Copper Chromium Nickel Silicon CuCrNi2Si – UNS.C18000 Copper Chromium Nickel Silicon Alloys, which also called Beryllium Free Copper alloy, meets the mechanical requirements of RWMA Class 3 Copper, is a very hard heat treatable copper based alloy with an economical higher strength and high conductivity, and C18000 Alloys is utilized when a combination of very good mechanical strength along with moderate electrical and thermal electrical conductivity are required. Furthermore, C18000 alloy is an excellent substitute for copper beryllium alloys C17500 and C17510 in terms of many applications. Typical Application for C18000 Copper Chromium Nickel Silicon Alloys: Industrial: Heat Sink Inserts in Steel Plastic Molds, Plunger Tips for Die Casting Metal Machines, Core & Ejector Pins for Injection Molds, Mold Cavities for Bold Molds, Welding Dies for Wires and Flash, Hot Runner Systems for Injection Molds, Stud Welding Collets and Tips, Resistance Welding Wheels and Fixtures, Resistance Welding Tips. Available Sizes: Custom Diameter & Sizes, Random Mill lengths Available Products (forms): Round bars, Flat bars, Square bars, Rectangular bars, Hexagon bars, Plates Custom shapes are available upon request. Chemical Composition: Cr: 0.10-0.80% Ni: 1.80-3.0% Si: 0.40-0.80% Cu: Balance Note: Copper plus additions equal 99.50% minimum. Typical Physical Properties: Specific Gravity: 8.84 Melting Point: 1074°C Coefficient of Thermal Expansion per °C: 16.2 x 10-6 (20-300°C) Electrical Conductivity (% IACS): 38 (22 Ms/m) Thermal Conductivity (W/mk): 200 Modulus of Elasticity (10 3 MPA): 130 Note: 1). the units are based upon US Customary. 2). the typical physical properties apply to age hardened products. International Specification: Rods/Bars/Plates/Sheets: UNS.C18000, CDA180, RWMA Class 3 European Standards: CuCrNi2Si, DIN 2.0855, CW111C to EN Note: ASTM: American Society for Testing and Materials RWMA: Resistance Welder Manufacturers' Association Note: Unless otherwise specified, material will be produced to DIN & RWMA. Mechanical Properties: The detailed Mechanical Properties will be available on request from customers. Most Commonly Temper Used: Rods/Bars/Tubes: AT(TF00), HT (TH04) Plates: AT(TF00), HT(TH04)
