Nickel silver, known also as German silver, nickel brass or alpacca, is a copper alloy with nickel and often zinc. Thermal conductivity is represented mathematically below: K = Thermal Conductivity (W/ (mK)) or (Btu/ (hrft*F)) Q = Amount of Heat Transferred (W) or (Btu) d = Distance Between the Two Isothermal Planes (m) or (ft) A = Surface Area (m) or (ft) T = Change in Temperature (K) or (F) Thermal conductivity varies greatly depending on the material. Thermal conductivity of a material is its ability to conduct heat. Light gases, such ashydrogenandheliumtypically havehigh thermal conductivity. Tool steel refers to a variety of carbon and alloy steels that are particularly well-suited to be made into tools (punches, dies, molds, tools for cutting, blanking, forming, drawing, steering and slitting tools). We realize that the basics in the materials science can help people to understand many common problems. Each type is manufactured differently. It is a white, mechanically rugged material and has a high chemical resistance. Precipitation-hardening stainless steels have high toughness, strength, and corrosion resistance. The data is listed on pages 6 through 8 and graphed on page 1 where Fenton and company are on curves 63 and 64. Although graphite is flexible, it is not elastic and has high electrical and thermal conductivity. Metals or alloys like galinstan that are liquids at room temperature are often used by overclockers and enthusiasts as a thermal interface for computer hardware cooling.
