For applications with higher contact forces and operating at higher temperatures contact oils with a higher viscosity are advantageous. Tungsten carbidesilicon carbidechromium carbideand aluminum oxide alumina are commonly used in composite electroplating. Depending on the alloy system, an electroplated alloy may be solid solution strengthened or precipitation hardened by heat treatment to improve the plating's physical and chemical properties. The use of screw terminal "chocolate blocks" in building wiring installations has sharply declined in favour of crimp, push and twist type connectors which are not prone to working loose and easier to fit. Using copper for plating is also much less expensive than when plating with precious metals such as gold and silver. At higher loads and in situations where contact separation occurs during the sliding operation thermal decomposition may be initiated which causes the lubricating properties to be lost. Instead of using organic solvent to remove ionic and nonionic residues — which did not offer an effective long-term cleaning solution and posed environmental hazards — newer, more efficient and environmentally friendly procedures have been developed. It wasn't until the s that televisions became a staple in most American households. The properties of these reflow tin coatings are comparable to those created by conventional hot tinning.
