Dallorian alloy
From Wookieepedia, the Star Wars wiki.
Dallorian alloy was a hard alloy that was naturally resistant to heat, making it popular among companies and corporations who mined minerals and metals. Jango Fett's custom made WESTAR-34 blaster pistols had Dallorian alloy plating, keeping them from overheating in a fast-paced battle. It was also used in the creation of certain segments of Boba Fett's first suit of Mandalorian armor.
