High Velocity Oxygen Fuel (HVOF) and High Velocity Air Fuel (HVAF) thermal spray systems have proven to be some of the most versatile spray systems over the last 20 years. They are especially useful for applying highly wear-resistant and corrosion resistant coatings. Alloys International sold the first HVOF system ever used in Australia, and still operate with various systems on a daily basis. All HVOF powders are available in a range of cuts to suit various spray systems such as the JP-5000, HV2000, and various HVAF systems.
