Brass in Sheet Metals
Brass features a durable and distinctive golden surface, combining strength with ease of processing. It is suitable for manufacturing precision and complex components as well as decorative brass parts
Brass is an alloy of copper and zinc. In sheet metal fabrication, the addition of zinc in varying proportions generally gives brass superior mechanical strength, hardness, and wear resistance compared to pure copper, while it retains good ductility and offers better machinability. Additionally, its distinctive golden appearance makes brass highly popular for decorative sheet metal applications. However, these advantages come at the cost of reduced electrical and thermal conductivity.
70% Cu + 30% Zn. It offers excellent deep-drawing, bending, and flanging properties, ensuring the material does not easily crack during forming. It features good corrosion resistance and yields a high-quality finish when polished or electroplated, making it the preferred choice for processing copper sheet metal parts.
62% Cu + 38% Zn. The most cost-effective general-purpose brass has higher strength than H70, but slightly lower plasticity. It can meet the needs of conventional bending and shallow stamping. It is also cheaper and has certain machinability, making it suitable for composite processes of sheet metal and a small amount of machining.
65% Cu + 35% Zn. Its properties fall between those of H70 and H62, offering a good balance of formability, weldability, and strength. It exhibits excellent brazing and gas welding characteristics, making it suitable for sheet metal structures requiring joining by welding.
80% Cu + 20% Zn. It has a higher copper content and a brilliant golden-yellow hue, offering excellent decorative appeal; it features stable plasticity and superior corrosion resistance, resists stress-induced discoloration during bending, and yields excellent results in surface polishing and anodizing.
It features a warm, reddish hue, excellent electrical and thermal conductivity, high resistance to dezincification, and good plasticity, making it suitable for shallow drawing and precision bending. It is commonly used for high-end decorative crafts.
Brass sheet metal parts naturally offer a warm golden appearance, good surface quality, and excellent machinability. However, the right surface finish can further improve corrosion resistance, wear performance, appearance, solderability, and long-term product reliability. At Longwang, we help customers select suitable finishing options based on part function, tolerance requirements, operating environment, and visual expectations.
As Machined
Standard finish, surface roughness of 3.2 μm (126 μin), removes sharp edges and deburs parts cleanly.
Tumbling
Utilizes barrel or vibratory processes with abrasives to smooth and polish the surface of parts.
Heat Treatment
Alters the physical (and sometimes chemical) properties of a material to achieve desired mechanical properties.
Anodizing
Electrochemical process that forms a durable, corrosion-resistant oxide layer on the surface of metals.
Electroplating
Electroplating is an electrochemical process that deposits a protective metal layer onto a conductive surface.
Polishing
Polishing smooths a surface to improve shine, reduce roughness, and enhance appearance.
Powder Coating
Powder coating provides a durable, scratch-resistant finish with excellent corrosion protection and a clean, attractive appearance.
Brushed
Brushed finish creates a refined linear texture with a modern, metallic look.
Brass is one of the most popular metals for sheet metal fabrication because it combines excellent machinability with good mechanical properties, corrosion resistance, and an attractive appearance. It is especially suitable for precision turned parts, fittings, connectors, bushings, valves, and decorative components.
pros
cons
Sheet metal brass parts are widely used across electronics, automotive, plumbing, smart home, industrial equipment, and precision hardware applications. Thanks to its machinability, corrosion resistance, conductivity, and premium appearance, brass is suitable for both functional and decorative components.
