Combustion wire spray systems using the 16E gun are an excellent choice for machine element applications, non-critical surface restoration, corrosion coatings, bond coats, sliding wear applications requiring self-lubricating coatings and on-site work such as bridges, water towers and marine applications. The standard 16E system is configured for use with hard wires, such as nickel, molybdenum, harder aluminum alloys and iron based wires.
