HARDFACING CORED WIRES
ADVANTAGES OF CORED WIRES
HIGH-PERFORMANCE HARDFACING
The tubular structure allows the integration of various alloying elements and carbides to obtain deposits tailored to specific wear constraints.
WIDE RANGE OF AVAILABLE ALLOYS
BMI offers a wide selection of hardfacing cored wires, allowing the deposit composition to be tailored to the constraints encountered in your process.
Our teams support you in selecting the most suitable wire to optimize wear protection and extend the service life of your equipment.
Different formulations cover a wide range of applications: abrasion, impact, friction, corrosion and temperature resistance.
HOMOGENEOUS AND CONTROLLED DEPOSIT
The controlled wire composition ensures a good distribution of carbides in the deposit, providing durable wear protection.
SOLUTION FOR MANUFACTURING AND REPAIR
Hardfacing cored wires allow the deposition of a metallic layer enriched with carbides to ensure long-lasting protection of components subjected to wear.
Thanks to controlled alloy formulations and tubular wire technology, they provide high flexibility and enable precise adaptation of the deposit to the wear mechanisms encountered: abrasion, impact, friction or high temperatures.
BMI offers a wide range of hardfacing cored wires for the manufacturing of new parts or the reconditioning of worn components.
