Scientists find new class of metal alloys that resist cracking at minus 423°F

Researchers have identified a new class of metal alloys that stay crack-resistant at around minus 423°F (about -253°C). The finding could support cryogenic hardware, spacecraft and superconducting systems.

• Alloys withstand cooling to minus 423°F without cracking
• Described as a new class of metallic materials
• Temperature equals roughly -253°C
• Potential use in cryogenics and space systems
