How much will liquid nitrogen shrink metal

WebSep 16, 2024 · The image above represents total volume shrinkage. To compute for total volume shrinkage, three essential parameters are needed and these parameters are Liquid Shrinkage of Metal or Alloy (εv.l), Freezing Shrinkage (εv.f) and Solid Shrinkage (εv.s). The formula for calculating the total volume shrinkage: ε v.t = ε v.l + ε v.f + ε v.s. WebYes it does. The standard linear expansion coefficient for brass is about 19x10-6 per degree C. To go from room temperature, 20 o C to the temperature of liquid nitrogen, -196 o C you would get an shrinkage factor of about 0.4 percent. Perhaps my pal MikeW knows if the linear expansion is valid at those temperatures.
