Copper 102 is an oxygen-free copper with extremely high electrical conductivity and good formability. These characteristics make it particularly useful for electrical connectors. Copper 102 can be deep-drawn from the annealed temper.It is corrosion resistant in normal atmosphere and water. A thin adherent oxide film forms at elevated temperatures which prevents particle contamination and enhances glass to metal seals. The Copper 102 can be readily soldered and brazed. The absence of oxygen makes welds free of inclusions. Available Sizes: Copper 102 is available from Hamilton Precision Metals as strip product in thicknesses from 0.0005” to 0.010” (0.0127 mm to 0.254 mm) in widths up to 12.0” (304.8 mm). The material conforms to ASTM B 152 and UNS C10200. It is also available in thickness less than 0.0005” (0.0127 mm) in widths up to 4.000” (101.6 mm) maximum.

Copper alloys exhibit very high electrical and thermal conductivities, offering twice the conductivity of aluminum and thirty times the conductivity of stainless steel. Other advantageous characteristics include outstanding strength (notably copper beryllium alloys) and corrosion resistance as well as antimicrobial properties. Copper is most commonly used in electrical and electronic applications.

Phosphor Bronze A is a Copper base spring material with a good combination of strength, formability, and corrosion resistance. The material is suitable for use in certain contact springs and diaphragms. The alloy has good formability up to moderate strength. It can be soldered, silver brazed, and resistance welded. Available Sizes: Phosphor Bronze A is available from Hamilton Precision Metals as strip products in thicknesses from 0.001” to 0.020” (0.0254 mm to 0.508 mm) in widths up to 12.0” (304.8 mm). The material conforms to ASTM B 103 and UNS C51000.

Beryllium Copper 25 is a Copper base alloy with the capability of being strengthened by precipitation heat treatment. The alloy furnishes the best combination of electrical conductivity, corrosion resistance and mechanical strength necessary for numerous electronic and electromechanical devices. The alloy is quite satisfactory for fabrication with good formability and joining characteristics. Forming is readily accomplished from the annealed temper. Severe bending will be less successful from hard or heat treated tempers and requires large fold radius ratios. Beryllium Copper 25 is able to be soldered, brazed, and welded by most standard techniques. The brazing temperature must be kept under 1450º F and cycle time minimized to avoid loss of heat treated strength. Heat treating should be performed subsequent to welding to obtain uniform high strength. The alloy is not susceptible to an increase in magnetic attraction from plastic deformation during service

Shunt Manganin is a Copper-Manganese resistance alloy used for shunts in various high current applications. The alloy has a low temperature coefficient of resistivity with peak resistance at about 50°C. The thermal EMF vs. Copper is very low. The alloy can be easily formed from the annealed temper.The maximum recommended operating temperature in air is 200°F. Available Sizes: Shunt Manganin is available from Hamilton Precision Metals as strip product in thicknesses from 0.0005 to 0.053” (0.0127 mm to 1.346 mm) in widths up to 12.0” (304.8 mm). It is also available in foil as thin as 0.000100” (0.00254 mm) in widths of 4.0” (101.6 mm) maximum.

Cu-Ni 715 is a copper-nickel alloy that is resistant to corrosion in sea water. The alloy has good fatigue strength and relatively high thermal conductivity. This alloy is used mainly for flexible metal foil heaters. The alloy is readily formed in the annealed temper, and can be joined by the standard welding, brazing and soldering processes. Available Sizes: Cu-Ni 715 is available from Hamilton Precision Metals as strip product in thicknesses from 0.0005” to 0.010” (0.0127 mm to 0.254 mm) in widths up to 12” (304.8 mm). The material conforms to ASTM B122 and UNS C71500.

Constantan® is a copper-nickel alloy that contains specific minor amounts of additional elements to achieve precise values for the temperature coefficient of resistivity. Careful control of melting and conversion practices results in a very low level of pinholes at ultra-thin thicknesses. The alloy is used extensively for foil resistors and strain gauges. The TCR can be adjusted from the furnished cold rolled values by using a low temperature heat treatment to achieve compensation for all types of spring elements. The foil is normally supplied with 90% cold reduction and a smooth bright surface. The foil is reasonably flat at 4” wide and nearly free of pinholes. The cold rolled foil can be produced with a TCR between +10 to –35 PPM/°C. The heat treatment will shift the foil TCR to the desired value. A typical heat-treat curve for Constantan® shows decreasing resistivity but increasing TCR with increased heat-treating temperature.

Hamilton Precision Metals is the world leader of precision-rolled foil and ultra-light gauge strip in any alloy. This includes stainless steel foil, titanium foil, nickel foil, copper based foil, cobalt based foil, Constantan® foil, Evanohm® foil, and many other alloys. Metal foil is generally defined as strip 0.004” (0.1016 mm) and below.
