View Sample Alloy Digest Data Sheet (PDF)Since 1952, Alloy Digest has been the leading reference for materials property data on metals and alloys used throughout the world. Featuring graphs, charts and tables, these sheets give facts and figures on composition or characterization, physical and mechanical properties, heat treatment, and machinability.AIRCO METAL-COR 6 is a continuous tubular steel welding electrode with a powdered-metal core; gas shielding rather than slag is used to protect the core. It eliminates 50 to 70% of the smoke and fumes generated by self-shielded flux-cored electrodes and about 30% of the smoke from gas-shielded flux-cored electrodes. Metal-Core 6 is used to deposit typically 1.6 to 1.8% manganese steel weld metal that provides as-deposited tensile strength in the range 85,000 to 92,000 psi, depending on composition of the shielding gas.
