No, metals always expand when heated and contract only when cooled.
It contracts when heated from 0 deg C to 4 deg C. Other substance expand when heated.
Titanium has a relatively low thermal expansion coefficient compared to other metals, meaning it expands less when heated. This property makes it useful in applications where dimensional stability is important.
Most substances expand when heated.
All those metals are considered to be Earth Elements, or substances that can be found on Earth and are pure since they can not be broken down into any other substances.
Among the alkali metals, the tendency to react with other substances increases form top to bottom within the group.Accompanying link shows the reaction from lithium through to cesium
Why do metals do not catch fire when heated whereas paper ignites on heating
An ore is a mineral that contains metals or other valuable substances in economically exploitable amounts. Ores are extracted through mining and processing to extract the desired materials.
A thermocouple is two different metals in contact with each other that generate a voltage when heated.
