Face-centered cubic or FCC metals are used for low temperatures because it is very ductile. This ductility allows for movable dislocations to occur in FCC metals.
no transition temperature
they have low reactivity
Its used because it has low reactivity, remains a gas at most temperatures and retains the pressure
Solder is a mixture of various metals. Its physical property is that it melts at fairly low temperatures, not so low that it melts when this is undesired. Its reactions are the same as the component metals.
low melting point and high conductivity
Alkali Metals
Yes
Cryogenic Processing of metals (i.e. metals frozen to low temperatures) show more resistance to wear
cryometer is used for to measure the low temperatures
sa515 IS USED FOR INTERMEDIATE TO HIGH TEMPERATURES AND SA 516 IS USED FOR LOW TO MEDIUM TEMPERATURES.
they have low reactivity
low temperatures
Continued exposure to low or rapidly falling temperatures.
Gold is used because it doesn't decay; most metals react with oxygen in the air and decay. Gold is also easy to work as it is soft and melts at relatively low temperatures, is an attractive colour and rare - making it valuable.
This is a steel with magnetic properties and is used for low temperatures.
a refrigerator for low temperature and a micro-wave for high temperature.
ceramics are the materials which are non metals which can be used over metals due to low co-efficient of friction
Lowering the temperature of a material can change it's molecular structure but it will still basically be the same material because the elements are still there.
