Starway is capable of brass sheet metal fabrication. H59 and H62 are two very common grade for brass material. Do you know the difference between them?

What are H59 Brass and H62 Brass?

Copper can be divided into electrolytic copper and copper alloy, then the copper alloy includes brass, bronze, and white brass (also called copper-nickel, paktong, or cupronickel). Brass is an alloy of copper and zinc; bronze is an alloy of copper and tin; white brass is an alloy of copper and nickel. Brass H62 and H59 are both a kind of copper alloy, as the game suggests, with copper content close to 62% and 59% respectively.

H62 brass refers to a type of ordinary brass with an average copper content of 62%, the "H" in H62 which from GB (Guobiao) standards, represents the first letter of the Pinyin of the Chinese character "Huang", and 62 represents the average content of copper. The ordinary brass added other elements called special brass, which is still represented by "H", followed by the added chemical symbols and their average composition. For example, HAl59-3-2 contains 57%-60% copper, 2.5%-3.5 aluminum, 2%-3% nickel and the remainder is zinc.

H59 brass is the cheapest brass with high strength, high hardness, and poor plasticity. It also can withstand pressure processing under the hot state, its corrosion resistance is average and other properties are similar to H62.

Performance and applications

H59 brass has cheap price and ordinary corrosion resistance, so it is generally used for machine parts, welding parts, hot stamping and hot rolling parts, suitable for electrical appliances, electronics, lighting, hardware, mounting horizontal, switch, gasket, battery contact piece, copper button, watch strap, decorative necklace, bracelet, ring and other brass products. H62 brass has good mechanical properties, good corrosion resistance and better plasticity in hot or cold condition, it is easy to machine, braze and weld, but also easy to produce corrosion cracking, it can be used for parts need to withstand large load and the is a good material for making faucets. Common uses of H62 brass including pin, nut, washer, radiator, sugar industry, shipbuilding industry, paper industry, and other parts.
