Note: H2-temper designations indicate that a different process has been used to achieve mechanical characteristics similar to those of the corresponding H1-tempers. However, property limits of H2-tempers differ from the above in that the Maximum Tensile Strength and Minimum Yield Strength provisions do not apply. Where required, material supplied in H2-tempers can be produced to meet the mechanical property limits of the equivalent H1-tempers.

Modulus of Elasticity: 69,000 MPa

Bend Radii: Minimum recommended internal bend radii for 90º cold bends at right angle to the rolling direction.

Welding: 3003 is readily welded by the TIG and MIG processes. Commonly used filler alloys are 4043 and 1100. 4043 gives a greater weld strength, but if the assembly is to be anodized, 1100 filler metal will give a closer color match.

3003 may also be gas welded or resistance welded, but the resulting joints are not as strong or as corrosion resistant as the inert gas welded joints. Moreover, gas welding could result in excessive heat distortion and, in thinner gauges, may burn through. It is essential that all traces of flux used in welding or brazing are removed by scrubbing with hot water upon completion.

Annealing: 415ºC ± 5ºC, until all parts have reached the annealing temperature.
Weight Calculation: Weight per square meter in kilograms: 2.73 x thickness in mm.

Note: 3004 is an alloy which spontaneously softens after rolling until it reaches a stable condition. This process is accelerated by means of a stabilizing anneal, giving the material an H3-temper. For this reason, 3004 is normally supplied in the H3-temper in which the stable condition is achieved before shipment.

Modulus of Elasticity: 69,000 MPa
Bend Radii: Minimum recommended internal bend radii for 90 cold bends at right angle to the rolling direction.

Note: 1)An alternative method of production, designated H2X, may be used instead of the H1X routes subject to agreement between supplier and purchaser and providing that the same specified properties are achieved.

2) BS 1470 does not specify minimum elongation for gauges under 0.50mm. The limit to be applied shall be subject to agreement between supplier and purchaser.
Modulus of Elasticity: 69,000 MPa

Bend Radii: Minimum recommended internal bend radii for 90 cold bends at right angle to the rolling direction.

Welding: 3103 is readily welded by the TIG and MIG processes. Commonly used filler alloys are 4043 and 1100. 4043 gives greater weld strength, but if the assembly is to be anodized, 1100 filler metal will give a closer color match.

3103 may also be gas welded or resistance welded, but the resulting joints are not as strong or as corrosion resistant as the inert gas welded joints. Moreover, gas welding could result in excessive heat distortion and, in thinner gauges, may burn through. It is essential that all traces of flux used in welding or brazing are removed by scrubbing with hot water upon completion.
Annealing: 415C 5C, until all parts have reached the annealing temperature.

Weight Calculation: Weight per square meter in kilograms: 2.73 x thickness in mm.

Alternative Designations: AS 3105; BS 3105 (formerly N31); DIN AlMn0.5Mg0.5; EN AW-3105; JIS A3105P; NF A 3105.

Characteristics:

Corrosion Resistance Very Good
Anodising Very Good (for surface protection)
Formability Very Good for soft temper
Machinability Poor
Weldability Very Good
Brazeability Good

Typical Uses: General sheet metal work requiring greater strength than is provided by 1000 series alloys; profiled building sheet (roofing and siding); flashings and ducting; panels; vehicle and caravan paneling; some hollowware; and domestic appliances.

Note: Special grades are available for deep drawing and spinning; general purpose grades should not be used for these operations. 3105 is not suitable for bright anodising. 3105 responds to architectural anodising better than 3003, but not so well as other commonly available alloys. Anodising should therefore be primarily for surface protection.

Note: 1)H2-temper designations indicate that a different process has been used to achieve mechanical characteristics similar to those of the corresponding H1-tempers. However, property limits of H2-tempers differ from the above in that the Maximum Tensile Strength and Minimum Yield Strength provisions do not apply. Where required, material supplied in H2-tempers can be produced to meet the mechanical property limits of the equivalent H1-tempers.

2) Tensile property limits for gauges outside of the indicated range shall be subject to agreement between Garmco and purchaser.
