Specification of Aluminium Extrusion

We confirm that the Aluminium Extrusions manufactured by us for architectural
purposes confirm to the following specifications.
Primary quality billets confirming to American Standard AA6063, Homogenized, and
LME registered with Fe content less than 0.2% is used to manufacture all our products.
All mill finish materials are hardened to yield a temper of T6 – T8.
Other standard physical and mechanical properties are as follows:-
Density - 2.7 g /cc
Hardness, Vickers - 76
Tensile Strength, Ultimate - 185 Mpa
Tensile Strength, Yield - 145 Mpa
Elongation at break - 12%
Modules of Elasticity - 69 Gpa
Shear Strength - 115 Mpa
Electrical Receptivity - 0.0000031 ohm – cm
Melting Point - 616 ºC
Two-step Anodizing / Electro Colour process is used. Anodic coating thickness to be
agreed by customer Maximum coat thickness available is 20 – 25 microns. Coating
thickness is measured on significant surfaces as per British Standard BS1615 of 1987,
BS6469 of 1984. Coating thickness ranges from (10 – 12), (15 – 20), (21 -25).
Powder coated materials are manufactured using architectural grade pure polyester
powder with high quality “Henkel” pre-treatment. Standard average powder coating
thickness is 60-80 microns on the significant surfaces as per BS1615. Powder used to
coat the products meet GSB, Qualicoat and and British Standards for weathering,
adhesion, impact, etc.
Every batch is tested prior to dispatch and carries a Company Warranty on all
manufacturing defects.
