We offer two Spinodal alloy grades produced through the same wrought powder metallurgy as copper based products with nickel and tin additions. Our Pfinodal® (C72900) and AM 388® (C72650) spinodal materials deliver similar mechanical properties to Beryllium Copper alloy (C17200) but without the carcinogenic exposure risks. Advantages include: No carcinogenic elements - only copper/nickel/tin Ductile state and heat treatable Electrically conductive Reduced distortion during heat treatment Reduced stress relaxation Safe Alternative to Beryllium Copper (UNS C17200) Recently, Pfinodal® and AM-388® have been chosen as a replacement for Beryllium Copper due to the carcinogenic effects of Beryllium and fears of bans on Beryllium containing products due to REACH, RoHS, and OSHA mandates. Spinodal materials are gaining acceptance in new projects as well as legacy qualifications as manufacturers, OEMs, and consumers reject products

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”

Our standard offering of nickel chrome strip products contain a chrome percentage ranging from 20%, 30% and 35% chrome (balance nickel). Silicon can also be added to the product to promote de-oxidation during the welding process The 35% chrome (AMETEK 835) is one of the highest chrome containing products offered in the industry and our high purity process allows for elongations above 45% for even those products containing silicon additions between 1% and 2%.

AMETEK Specialty Metal Products has applied the high purity wrought powder compaction process to Ductile Cobalt Alloys in order to produce multiple ductile cobalt strip products generally used by weld wire manufacturers as sheathing for flux cored and metal cored hardfacing materials. These alloys range from 80 to 95% cobalt with Iron or Iron-Nickel additions to improve ductility for drawing operations.

Titanium for Implantable Medical Devices Ti 6Al/4V ELI sheet has found application in medical implants owing to its excellent biocompatibility, high strength, and MRI compatibility. In the cold rolled and annealed temper the material will not exhibit a continuous alpha network at prior beta grain boundaries or a continuous alpha case layer on the surface. Owing to the alloy’s high strength and low ductility, it is difficult to cold draw into finished shapes. Hot forming has been found to be effective.

Our specialized Pfinodal® C72900 material is a Spinodal copper based alloy with nickel and tin additions. It competes with Beryllium Copper alloy C17200 for electrical connectors and bearing materials where high strength and excellent formability without dimensional instability are required.

Our roll bonded clad plate products are engineered for demanding ASME pressure vessel, steam boiler and autoclave applications where high corrosion resistance, pressure resistance and structural performance are critical. Using proven roll bonded technology and corrosion resistant alloys, our high strength clad plate is manufactured to exacting pressure vessel specifications and certified to ASTM A263, A264 or A265 for pressure vessel fabrication. Corrosion Resistant Alloys We specialize in processing high corrosion resistant alloys and BPVC rated materials for stainless steel pressure vessel manufacturers. Other alloys include: Stainless Steels Nickel and Nickel Alloys Inconel®, Monel®, Hastelloy® Aluminum Carbon steel Titanium Other alloys available upon request

Nickel 201/200 strip (899L) is our premier battery grade that offers improved conductivity over Nickel 200 and Nickel 201 strip while maintaining closer mechanical properties to the lower conductivity materials.
