Product catalog summary
Product Description: The document describes a high-strength 4 to 5% Copper alloy, available in extruded bar and profile form, fully heat-treated (solution heat-treated and artificially aged). It is typically stocked in the T6511 condition, except for sizes under 10mm and over 203.2mm diameter, which are T6 only. The alloy is equivalent to 2014AT6 and conforms to various standards including EN 573/755 and BS EN 2384, 2635.
Surface Treatment: The alloy can undergo anodising with fair protective and colour results, but is unsuitable for bright anodising. It has good hard anodising properties and very good plating capabilities. Vitreous enamelling is unsuitable.
Chemical Composition: The alloy's composition includes Aluminum (remainder), Silicon (0.50-0.90%), Iron (max 0.50%), Copper (3.90-5.00%), Manganese (0.40-1.20%), Magnesium (0.20-0.80%), Zinc (max 0.25%), Titanium (max 0.15%), Nickel (max 0.10%), and others (max 0.15% each).
Mechanical Properties: The document lists minimum tensile strength and proof stress for various size ranges, with elongation percentages provided for specific conditions.
Technical Assistance: The company offers support from qualified metallurgists and engineers for technical inquiries.
Production Tolerances: Manufacturing limits adhere to BS L100 standards. Further assistance is available through the Sales Department or Laboratory.
Weldability: The alloy is not recommended for brazing, soldering, or oxygen welding, but has excellent resistance, spot, and beam welding capabilities.
Corrosion Resistance: The alloy has poor resistance to atmospheric attack, especially in water or salt environments. A lanolin-based protective oil is recommended for storage protection.
Machinability: The alloy is noted for very good machinability.
Disclaimer: The information is based on approximate testing and does not constitute a guarantee of properties or processing possibilities. Warranties and liabilities are detailed in the company's terms of trading.
