Alloy 2219
Product catalog summary
Overview: This document provides detailed information on the chemical composition, physical properties, and mechanical properties of Alloy 2219 in various tempers. It is intended for comparison purposes and not for engineering specifications or design.
Chemical Composition Limits: The document specifies the weight percentage limits for key elements in Alloy 2219, including Copper (Cu: 5.80-6.80%), Magnesium (Mg: 0.02-0.20%), Manganese (Mn: 0.20-0.40%), Silicon (Si: 0.20%), Iron (Fe: 0.30%), Zinc (Zn: 0.10%), and Titanium (Ti: 0.02-0.10%).
Typical Physical Properties: The average coefficient of thermal expansion is 12.4 (68-212°F per F), and the melting range is approximately 1010-1190°F. Thermal conductivity at 772°F is 1190 English units, and electrical conductivity at 682°F is 28-30 equal volume and 88-94 equal weight.
Mechanical Properties: The document lists typical mechanical properties for different tempers of Alloy 2219, including tensile strength, yield strength, elongation, Brinell hardness, ultimate shearing strength, fatigue endurance limit, and modulus of elasticity. For example, the tensile strength ranges from 25 KSI for 2219-0 to 69 KSI for 2219-T87, with corresponding yield strengths and elongation percentages.
Disclaimer: The properties listed are averages and not guaranteed for specific products or sizes. They are intended for comparison and should not be used as engineering requirements.
