The Zirconia - stabilised with Yttria Nut is one of a range of nuts from Goodfellow, and comes in 3 variations. This advanced ceramic material is known for its high strength, fracture toughness, and thermal shock resistance. The addition of yttria helps stabilize the tetragonal crystal structure of zirconia. Potential applications for yttria-stabilised Zirconia Nuts include use in high-temperature environments like gas turbines and internal combustion engines. The Goodfellow range allows customers to select the optimal nut design for specific applications.
