Tin is a soft, malleable, ductile and highly crystalline silvery-white metal. When a bar of tin is bent a crackling sound known as the "tin cry" can be heard from the twinning of the crystals. Tin melts at about 232 °C (450 °F) the lowest in group 14. The melting point is further lowered to 177.3 °C (351.1 °F) for 11 nm particles. Commercial grades of tin (99.8% tin content) resist transformation because of the inhibiting effect of small amounts of bismuth, antimony, lead, and silver present as impurities. Alloying elements such as copper, antimony, bismuth, cadmium, and silver increase the hardness of tin. Tin easily forms hard, brittle intermetallic phases that are typically undesirable. It does not mix into a solution with most metals and elements so tin does not have much solid solubility. Tin mixes well with bismuth, gallium, lead, thallium and zinc forming simple eutectic systems. Tin resists corrosion from water, but can be corroded by acids and alkalis. Tin can be highly polished and is used as a protective coat for other metals, a protective oxide (passivation) layer prevents further oxidation. Tin acts as a catalyst triggering a chemical reaction of a solution containing oxygen and helps to increase the speed of the chemical reaction that results. Therefore, tin signs are very stable in daily life.

Home decoration tin signs include garage metal signs, animal tin signs, food tin signs, wall decoration tin signs, etc. Metal electroplating and electroforming nameplates are also known as gold stacking signs. It is a method of using screen printing or photosensitive plate making to coat the plate and then use electroplating. Let the text and lines pass through the pre-plated, cast copper, nickel, gold-plated books to form raised gold-plated gold medals. It can complete different patterns and texts of various fonts according to the requirements of users. The products are durable and non-corrosive, not afraid of rain and sun, wear-resistant and non-fading. Beautiful and generous, with bright colors, clear patterns and good brightness, it is an indispensable car body sticker for various electronic products, automobiles, household appliances, etc.
