Laser Alloying
( Aluminum Brake Disc )
After studying for a few of years, Yiu Hwa Technology Co. has been succeeding the laser alloying in Aluminum alloy products, like aluminum alloy brake disks and aluminum alloy pistons. Laser alloying is a process of melting additive material, such as Nickel, Chrome alloy or metal matrix of ceramic powder, and substrate aluminum metal or other metal by high power-density laser beam. Laser beam exits high energy and low heat effected characteristic, and it progresses the surface modification very well for modifying the wearing, bearing, corrosion and temperature properties of aluminum alloy or other metals.


Aluminum alloy disks with laser alloying in bicycle or machinery have more resistance in wearing property especially in higher temperature environment than the one without alloying. Comparing with stainless disk, there exists similar wearing property but the aluminum disk has lower or only one third of temperature than on the surface of stainless disk during working. Beside temperature rising, stainless also exits three times of in density when comparing with aluminum. Considering the strength and stiffness of a disk, aluminum alloy has similar serving life with stainless, but the weight is only one half in aluminum alloy, and the temperature is around one third in laser alloying disk, such as 450 $ in stainless and 150$ degree during the serious serving. Thus, the hydraulic breaking system will be avoiding damage during the service period when the alloying aluminum alloy disk is used.
