Copper and Brass
When it comes to custom copper and brass stamped parts, we are experts in our field with the experience and know-how working with various types of Types and Alloys. We can design and manufacture your parts while providing the best match for your application from a wide variety of applications.
Copper is a chemical element. It is a soft, malleable, and ductile metal with very high thermal and electrical conductivity. Copper is used as a conductor of heat and electricity, as a building material, and as a constituent of various metal alloys. Integrated circuits and printed circuit boards increasingly feature copper in place of aluminum because of its superior electrical conductivity; heat sinks and heat exchangers use copper because of its superior heat dissipation properties. Due to its superior conductivity, it is often used in electrical motors
Brass is an alloy of copper and zinc, in proportions which can be varied to achieve varying mechanical and electrical properties. Brass has long been a popular material for decoration for its bright gold-like appearance. It is also widely used for its workability, durability, electrical and thermal conductivity. It is still commonly used in applications where corrosion resistance and low friction is required, such as locks, hinges, ammunition, plumbing, hose couplings, valves, and electrical plugs and sockets. The composition of brass, generally 66% copper and 34% zinc, makes it a favorable in high corrosion environments. Today, almost 90% of all brass alloys are recycled.
|Material Type and Alloy
|Benefits and Applications
|With a controllable grain size excellent for most cold forming qualities.
|1/4 Hard Temper
|Suitable for moderate drawing and forming requirements, with a small amount of stiffness.
|1/2 Hard Temper
|Suitable for light draws, blanking or stamping when some stiffness is required. Great for hinges, hardware and brackets.
|Excellent stamping qualities for fasteners, electrical parts, and parts needing extra strength.
|Has a high tensile strength when elongation is required. Good for relay contacts, mechanical springs, and flatform springs in electrical applications.
Brass CDA 260. Eight tempers are available for any application requirement.
We purchase certified materials including all chemistry details. This allows us the ability to trace every finished part back to the actual raw material heat and lot, as well as size, grade, Rockwell hardness, and temper.
Copper Beryllium (BeCu) (ASTM B194, B196, B197)
This material offers many benefits, including the greatest strength of all copper-based, conductivity that maintains the flow of electrical and thermal energy, improved miniaturization that allows smaller parts and connectors that have high a repetitive cycle life. Copper is known as a soft metal, whereas BeCu is used for its strength. Perhaps the most common uses for BeCu are in electronic connectors, telecommunications products, computer components, and small springs. BeCu is extremely versatile and known for: High electrical and thermal conductivity and high ductility. BeCu is expensive and weaker than alternatives like steel, but its non-sparking property heightens its value. ... Depending on the amount of Beryllium alloyed with the copper, it is divided into two categories-high strength and high conductivity.
Phosphor Bronze (ASTM B103, B139, B159)
This material has very good resistance to corrosion and fatigue, with good electrical conductivity. It’s best for when strength is needed in the application and has a low coefficient of friction with a fine grain and excellent elasticity. This is commonly used for spring forms and fasteners when bending and drawing is needed in the design. It is often found in the electronic, electrical, communications, dental, and automotive electronics industries.
