Tin—lead coatings (10—60 wt % tin) can be applied by hot-dipping or electrode position to steel and copper fabricated articles and sheet. A special product is teme plate used for roofing and flashings, automobile fuel tanks and fittings, air filters, mufflers, and general uses such as covers, lids, drawers, cabinets, consoles for instruments, and for radio and television equipment. Teme plate is low carbon steel, coated by a hot-dip process with an alloy of tin and lead, commonly about 7—25 wt % tin, remainder lead. Electroplating is another possibility. 

Teme is steel sheet that is hot dip coated with a lead-tin alloy [20]. Because lead does not readily wet steel, 2-25 % tin is added in order to ensure wetting and bonding of the coating to the substrate. Typical coating thicknesses are in the range of 5-15 pm. The product has good weldability, solderability, and formability. Largest applications have been in the automobile industry, particularly for fuel tanks.

Advancements in materitJs have been one of the most important factors in the development of corrosion-resistant automobiles. For automobile body and chassis parts, use of precoated sheet steel in critical areas, as demonstrated in Fig. 5, is one of the most effective methods of combating corrosion. Early on, hot dip gttlvanized steel and Zincro-metal coated steel were used to prevent perforation corrosion from the inside out in auto-body applications. Today a wide range of materi tls is used including hot dip and electrodeposited zinc, zinc-iron, zinc-nickel, and zinc-nickel/ organic composite coated steel. Other materials include aluminum and aluminum-zinc coated steels for exhaust systems and some structural components, teme (tin-lead) coated steel for fiiel tanks, and tin coated steel [23-25],... 

An alloy of lead containing 3 to 15% Sn, used as a hot dip coating for steel sheet or plate. Teme coatings, which are smooth and dull in appearance, give the steel better corrosion resistance and enhance its ability to be formed, soldered, or painted. 

Adhesives recommended include epoxies, vinyl alcohol—vinyl acetate copolymer, polyvinyl alkyl ether, polyacrylate (carboxylic), polyurethane (two-part), epoxy-phenolics, silicones, and cyanoacrylates. The high-strength thermoset and alloy adhesives are rarely justified for bonding lead. Even when other properties recommend these adhesives, the designer should check to see whether some low-cost or easier-to-use adhesive is also suitable. An exception is teme (lead-coated steel). This is a much stronger metal than lead, and lap-shear strengths exceeding 2.1 MPa are reported for adhesive joints with teme.° ...
