Types of Hafnium Coil

99.95% Hafnium Foil

99.95% hafnium foil refers to an extremely thin sheet made of hafnium metal with a purity of up to 99.95% (usually referred to as 3N5 grade) through precision processes such as rolling. This purity level means that its total impurity content is strictly controlled below 0.05%, making it a high specification product in hafnium foil designed to cope with extremely harsh application environments.

Acid Resistant Hafnium Foil

Acid resistant hafnium foil is a special foil material made from high-purity metal hafnium (≥ 99.9%) as the substrate, through precision rolling and surface treatment. It is a key material in the fields of chemical engineering, nuclear energy, and high-end manufacturing.

Surface treatment OF Hafnium Coil

Annealing

Annealing is a heat treatment process mainly used in metallurgy to increase the ductility and reduce the hardness of a material. This change is caused by the reduction of number of dislocations in the crystal structure of the material that is annealed. A lot of times, annealing is performed after a material has undergone a hardening or a cold working process. Annealing prevents such materials from becoming brittle or increase formability.

Pickling

Pickling is a metal treatment process used to remove superficial impurities from metal. It involves the use of an acidic solution known as pickle liquor, which contributes to the name.
The main step involved in pickling is the treatment of the target material in acidic solution. The metal is submerged in pickle liquor, which erodes any oxide or other impurities remaining on the surface of the metal.
