  • Patent number: 6593010
    Abstract: A composite material and a method of making a composite material is disclosed. The composite comprises a core of a precipitation hardenable metal having a coefficient of thermal expansion less than 9 parts per million/° C. in the temperature range of 20° C. to 100° C. The core material is clad with a transition metal or transition metal alloy cladding layer covering at least one surface of the core.

  • Patent number: 4366210
    Abstract: Thermostat metals combining properties of relatively high flexivity and good corrosion resistance are prepared by metalurgically bonding a corrosion resistant high expansive alloy (1) to a less corrosion resistant low expansive alloy (2) and capping the low expansive alloy (2) with a corrosion resistant, moderately low expansive alloy (3) of similar hardness to that of the low expansive alloy (2).The preferred high expansive alloy (1) is comprised of about 18 wt. % Ni; 11 wt. % Cr; and balance Fe.The preferred low expansive alloy (2) is Invar (36 wt. % Ni; balance Fe).The preferred corrosion resistant low expansive alloy (3) is comprised of about 20 wt. % Ni; 26 wt. % Co; 7 wt. % Cr; balance Fe.The preferred volumetric ratios of the metals is about 50% of the high expansive alloy (1), 30 to 40% of the low expansive metal (2) and 10 to 20% of the corrosion resistant low expansive alloy.

  • Patent number: 4115624
    Abstract: Thermostat metal compositions are disclosed which have a substantially uniform flexivity over a broad range of operating temperatures and which respond rapidly to changes in ambient temperatures. These results are achieved by using, as an intermediate layer, a major portion by volume of a thermostat metal that has a thermal conductivity in excess of 2,400 BTU in/ft.sup.2 hr.degree. F.
