1050 aluminium for sheet metal parts: grade and formability
1050 aluminium grades, tempers, thickness tolerance and formability: what the 99.5% purity buys, where it marks, and the bend and weld limits to design to.

Materials and grades
Most sheet metal problems are material decisions made too late. This cluster covers grade selection, thickness and tolerance, formability and corrosion for the materials Ganesh cuts, forms, welds and coats: CRCA and hot-rolled steel, 304 and 316L stainless, 5052 and 6061 aluminium, brass and copper. Each guide names the standard, the property that matters and the failure it prevents.

Grade selection for CRCA, stainless, aluminium, brass and copper: formability, thickness, corrosion and what the mill certificate actually guarantees.
When 6061 aluminium is the wrong material for a part
Five conditions where 6061 aluminium costs more and performs worse, the grade that replaces it, and the weight arithmetic that decides the swap.

When galvanised steel is the wrong material for a part
Six situations where galvanised sheet loses to CRCA, pre-painted coil, aluminium, stainless or post-fabrication hot-dip, with the fit and weld numbers.
Read
When brass is the wrong material for a part
Brass suits a narrow set of parts. Here are the failure modes, the cheaper substitutes and the stiffness and conductivity numbers behind the switch.
Read
Copper corrosion and finish compatibility
How copper behaves bare, powder coated or painted: patina rates, galvanic couples, oxide under the film, and the pretreatment the part needs before coating.
Read
6061 aluminium corrosion and finish compatibility
How 6061 aluminium behaves bare, powder coated, painted and anodised, the galvanic couples that pit it, and the cure limit its T6 temper sets.

Galvanic corrosion in mixed-material assemblies
Galvanic corrosion in sheet metal assemblies: the series, the area ratio, the current that removes metal, and the joint details that break the couple.

Material grade substitution: when a cheaper grade works
Material grade substitution without breaking fit, finish or certification: the five checks, the gauge arithmetic, and the cases where the change is refused.

When 430 stainless is the wrong material for a part
When 430 is the wrong material: the welded, wet and cold duties it cannot carry, the substitution numbers, and whether 304, 444 or coated CRCA fits.
