Metal foils - Import export

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. Cold rolling strip to these extremely thin gauges demands extensive rolling expertise to manufacture with precision and consistency.

HPM® 80/20 A is a resistance alloy used in electric heating applications. It is recommended for use in dry air applications up to 2150°F with good hot strength. Such as, flexible metal foil heaters and airbag igniters. The alloy forms rather well and has good welding characteristic. Caution should be used to avoid extended exposure to elevated temperature in marginally oxidizing or partially reducing atmospheres as it would be susceptible to “green rot” corrosion, carburization and sulfurization. Available Sizes: HPM® 80/20 A is available from Hamilton Precision Metals as strip product in thicknesses from 0.0005” to 0.050” (0.0127 mm to 1.27 mm) and width up to 12” (304.8 mm). The material conforms to ASTM B-344. Foil product may be supplied in thickness to 0.0001” (0.00254 mm) in width up to 4.0” (101.6 mm).

Evanohm® R is a unique resistance alloy with high electrical resistivity and very low temperature coefficient of resistivity (TCR). The alloy is produced by melting and conditioning practices which result in a low level of pinholes at ultra-thin thicknesses. This combination of attributes with inherent corrosion resistance makes it suitable for a variety of strain gauge, foil heaters and airbag igniters. The alloy is supplied with 90% cold reduction which has a positive TCR of about 70 PPM/ºC. A stabilizing heat treatment (approximately 475ºC) during manufacture of finished parts adjusts the TCR to a desired value. The heat treatment virtually eliminates any drift tendency of the resistivity. A heat-treat curve for each melt is developed at Hamilton and is made available as a guide in regulating TCR. Sizes Evanohm® R is available from Hamilton Precision Metals as foil and strip product in thicknesses from 0.0005” to 0.010” (0.0127 mm to 0.254 mm) and in widths up to 12.0”

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.

HPM® 600 is well suited for severe corrosive environments and is oxidation resistant through 2150°F. Such as, metal diaphragms for aerospace sensors, flexible metal foil heaters and metal diaphragms for burst discs. The strength can be increased by cold working. The material has good elevated strength retention through 800°F. The alloy is readily formed in the annealed temper, and can be joined by the standard welding, brazing and soldering processes. Available Sizes: HPM® 600 is available from Hamilton Precision Metals as strip product in thicknesses from 0.0005” to 0.050” (0.0127 mm to 1.27 mm) and width up to 12” (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. The material conforms to ASTM B168, AMS 5540, MIL N 23228 and UNS N06600.

HPM® 965 is a high purity Nickel-Iron alloy that exhibits moderate electrical resistivity and a high temperature coefficient of resistance. This combination of electrical characteristics makes it suitable for use as a self-regulating heating element or temperature sensor, such as use in flexible metal foil heaters. The alloy can be readily formed in the annealed temper and can be joined by standard welding methods. Available Sizes: HPM® 965 is available from Hamilton Precision Metals as foil and strip product in thicknesses from 0.0005” to 0.015” (0.0127 mm to 0.38 mm) and in widths up to 12” (304.8 mm). It is also available as thin as 0.000100” (0.00254 mm) and in widths up to 4” (101.6 mm) maximum.

HPM® 201 Nickel is a commercially pure wrought Nickel. With low carbon, the material has excellent corrosion resistance with high thermal and electrical conductivities. Making it perfect for use in flexible metal foil heaters. The alloy can be formed by all conventional cold-forming methods and can be joined by welding, brazing and soldering. The corrosion resistance is generally very good in most mediums, although it is subject to intergranular embrittlement by sulfur compounds above 315°C. Available Sizes: HPM® 201 Nickel is available from Hamilton Precision Metals as strip product in thicknesses from 0.0005” to 0.020” (0.0127 mm to 0.508 mm) in widths up to 12.0” (304.8 mm). It is available as foil as thin as 0.000100” (0.00254 mm) to 4.0” (101.6 mm) maximum width. The material conforms to ASTM B162, and UNS N02201.

Titanium exhibits a unique combination of properties including excellent corrosion resistance, high temperature resistance, and outstanding strength to weight ratios. Titanium is produced as commercially pure or alloyed. Commercially pure titanium is typically used in implantable medical applications whereas the titanium alloys are produced with the addition of vanadium or aluminum for applications such as aerospace. Hamilton Precision Metals processes strip and foil products in Titanium CP (Grade 1, Grade 2, Grade 4) and Titanium 3Al-2.5V (Grade 9).
