This may be the 1896 medal from Hungary that has been reported; it is possible that the latter was made from 'pure' tellurium. Jae-Sung RYU, Eun-Kyun CHUNG, Yong-Deok TARK. Two electrical contacts maintain an arc erosion resisting capability at the condition of a low contact resistance when the electrical contact material is formed on a surface of a metal substrate of an electric connector. In view of this, one expects fatigue life, or the number of cycles to failure, to be strongly temperature dependent. Yuning LI, Yiliang WU, Hualong PAN, Ping LIU, Paul F. SMITH, Hadi K. MAHABADI. An example of such use is the Canadian 5c pieces of 1944-45 and 1951-1954, which were nickel-plated steel with a surface plating of chromium to add wear resistance. Thereby, the probe pin usable in a stable manner for a long period of time can be obtained. A certain alloy contains 5.25 copper pipe. 31 kg/litre, 1545 C. Scarcest of the lanthanides. The metal work-hardens quickly which makes striking coins more difficult than silver or gold. Now, the percentage of the alloy as copper is $5. The same is true of the high-lead solders. The addition of magnesium improves the hardness and corrosion resistance of aluminium.

Abstract: The present invention relates to a silver braze alloy having improved wetting properties. A certain alloy contains 5.25 copper steel. Generally, solder alloys are based on the metals tin, lead, cadmium, zinc and indium. Aluminum master alloys help metallurgists fine-tune alloys to create materials that are stronger, lighter, and more easily processed Aluminum is the most abundant metallic element in the Earth's crust—it's even more common than Iron. Generally the alloys used vary in composition from 3% zinc to 30% zinc, and vary in colour from the red of copper to a bright yellow.

Abstract: The invention provides a method of treating sensitive teeth comprising attaching a sealant composition comprising a basic amino acid to a person's tooth and allowing the basic amino acid to be slowly released over time in order to reduce chrome and/or acute tooth sensitivity together with compositions and methods of use. A Guide to Coins of the UK. Sources of lead, cadmium, hexavalent chromium and mercury for such exemptions can easily be identified with a single look into Annex III or Annex IV of the RoHS Directive (2011).

Because it casts well and has a silvery appearance when new it has often been used for forgeries, especially when plated to replicate gold coins.
