Wettability is one of properties between liquid and solid material and it is very important factor affecting on acoustic property, corrosion property and so on. In this study, some experiments of wettability of pure metals were performed using the low-melting temperature alloy in order to get many fundamental information of wettability. The low-melting temperature alloy consists of bismuth, tin and indium. Aluminum, titanium, iron, nickel, copper, zirconium, niobium and molybdenum were used as a substrate metal. Test temperature was 353K and test atmosphere was in air. A droplet of the low-melting temperature alloy was put on the substrate metal and a contact angle was measured. From the measurement results, the contact angle changed depending on the substrate metal. It is suggested that the contact angle has relations with the atomic bonding between the s
