Low melting temperature allows repairing pewter and zinc objects, including die-cast toys. Sn 50 Pb 32 Cd 18: 145 [16] Cd, Pb: Cd18: Cd 82.5 Zn 17.5: 265 [27] Cd: Yes: Medium temperature alloy that provide strong, corrosion-resistant joints on most metals. [27] Also for soldering aluminium and die-cast zinc alloys. [28]
Tin-silver-copper (Sn-Ag-Cu, also known as SAC), is a lead-free alloy commonly used for electronic solder.It is the main choice for lead-free surface-mount technology (SMT) assembly in the industry, [1] as it is near eutectic, with adequate thermal fatigue properties, strength, and wettability. [2]
Has variety of applications but used rarely due to high melting point. Close temperature match for heat treating carbon steel, allows brazing and heat treating in a single step. Strength generally higher than of base metals. Maximum service temperature 149 °C, intermittently 260 °C. 45: 35: 20: Cu 52.5 Zn 22.5 Ag 25: Ag–Cu–Zn 675/855 [37 ...
Aluminium soldering alloys generally have melting temperatures around 730 °F (388 °C). [12] This soldering / brazing operation can use a propane torch heat source. [13] These materials are often advertised as "aluminium welding", but the process does not involve melting the base metal, and therefore is not properly a weld.
Soldering performed using alloys with a melting point above 450 °C (840 °F; 720 K) is called "hard soldering", "silver soldering", or brazing. In specific proportions, some alloys are eutectic — that is, the alloy's melting point is the lowest possible for a mixture of those components, and coincides with the freezing point.
The Gmelin rare earths handbook lists 1522 °C and 1550 °C as two melting points given in the literature, the most recent reference [Handbook on the chemistry and physics of rare earths, vol.12 (1989)] is given with 1529 °C.
Additionally, for a given fixed homologous temperature, two materials with different melting points would have similar diffusion-dependent deformation behaviour. For example, solder (T mp = 456 K) at 115 °C would have comparable mechanical properties to copper (T mp = 1358 K) at 881 °C, because they would both be at 0.85T mp despite being at ...
The solidus temperature specifies the temperature below which a material is completely solid, [2] and the minimum temperature at which a melt can co-exist with crystals in thermodynamic equilibrium. Liquidus and solidus are mostly used for impure substances (mixtures) such as glasses , metal alloys , ceramics , rocks , and minerals .
