... at pinholes through the coating. Tin is not electropositive under oxidizing conditions. but under some nonoxidizmg conditions. the potential of the tin-iron couple reverses. which accounts for the fact that tin does prevent exposed iron from corroding. The best example is on the inside of tinned cans. where...

... at temperamres up to approximately 200┬░C. Special melting and conditioning practices result in a low level of pinholes at ultrathin thiclcnesses. This combiion of at- tributes with inherent corrosion resistance makes it suitable for a variety of strain gage and foil resistor applications. The alloy is supplied...
