Sheet Metal
Material Library
Explore mechanical properties, chemical composition, and optimal coating pairings for 8 precision-grade alloys.
Aluminum 5052 (Marine Grade)
The most widely used alloy for precision sheet metal. Excellent strength-to-weight ratio, outstanding formability, and superior marine-atmosphere corrosion resistance.
Structural Aluminum 6061
Heat-treated silicon-magnesium aluminum with high structural strength. Widely used for CNC machining and bending with adequate radii.
Stainless Steel 304 (V2A)
Versatile chromium-nickel austenitic stainless steel with excellent ductility, toughness, and corrosion resistance. Widely used in food, medical, and industrial applications.
Stainless Steel 201 (Economy)
Manganese-substituted austenitic stainless steel offering a cost-effective alternative to 304. Widely used in decorative and general-purpose fabrication.
Cold Rolled Carbon Steel (SPCC)
Commercial-quality cold-rolled mild steel with excellent dimensional accuracy and smooth surface finish. Requires protective coating for corrosion resistance.
Electro-Galvanized Steel (SECC)
Cold-rolled steel with uniform electroplated zinc coating providing sacrificial corrosion protection. Ideal for indoor and mild outdoor applications.
Galvanized Steel Sheet (SGCC)
Steel with hot-dip zinc coating for outdoor corrosion protection. The zinc layer acts as both barrier and sacrificial anode.
Pure Copper C110 (ETP)
Electrolytic tough pitch copper with exceptional electrical and thermal conductivity. The material of choice for electrical busbars and heat transfer applications.
Aluminum 3003 (General Purpose)
The most economical workhorse aluminium alloy for formed sheet metal. Excellent corrosion resistance and formability, widely used for enclosures, panels and decorative parts where high strength is not required.
Stainless Steel 316 (Marine Grade)
Molybdenum-bearing austenitic stainless steel with superior corrosion resistance to 304, especially against chlorides and marine environments. The preferred grade for coastal, chemical and medical duty.
Stainless Steel 316L (Low Carbon)
The low-carbon variant of 316, optimised for welded construction. The reduced carbon content prevents sensitization and intergranular corrosion in the heat-affected zone, so post-weld heat treatment is rarely needed.
Structural Carbon Steel Q235
The most widely used Chinese structural carbon steel, the equivalent of A36 / S235JR. Excellent weldability and economy for load-bearing brackets, frames and structural sheet parts that are protected by a finish.
Cartridge Brass C26000 (70/30)
The classic 70/30 brass — 70% copper, 30% zinc — offering the best balance of ductility and strength of the brasses. Ideal for deep-drawn shells, decorative hardware and electrical contacts.
Brass H62 (60/40)
The most common Chinese brass grade (about 60% copper, 40% zinc). Lower cost and slightly higher strength than 70/30 brass, well suited to stamping, machining and general decorative and structural brass parts.
Phosphor Bronze C5191 (Spring Grade)
A copper-tin-phosphorus alloy prized for high strength, fatigue resistance and spring properties. The standard material for electrical springs, connectors and wear strips that must keep their shape.
Stainless Steel 314 (Heat Resistant)
A high-chromium, high-nickel, silicon-bearing austenitic stainless steel built for high-temperature service. The added silicon forms an adherent scale-resistant oxide, making it the grade for furnace parts, heat shields and continuous high-heat duty.
Aluminium 1050 / 1100 (O temper)
Commercially pure aluminium in the annealed O temper, with at least 99.0% aluminium content. Very little alloying means no precipitation-hardening response, so it is chosen for formability, weldability and a clean finish rather than for strength.
Stainless Steel 430 (Ferritic)
A chromium ferritic stainless with no nickel added. It resists ordinary atmospheric corrosion well and is markedly cheaper than the austenitic grades, but it is magnetic and it will pit in chloride environments.
Hot-Rolled Pickled Carbon Steel (SPHC)
Hot-rolled carbon steel that has been pickled to remove the mill scale, leaving a clean, scale-free surface. It arrives in heavier gauges than cold-rolled SPCC and is the usual base for parts that will be subsequently machined or coated.
Spring Steel 65Mn
A high-carbon manganese spring steel supplied in the annealed condition. It is the standard leaf-spring and spring-steel grade, valued for its very high elastic limit and ability to take repeated loading.
