white aluminum trim coil also called thermal insulation aluminium roll, heat insulation aluminium roll.
The selection of ship sheet materials is more stringent. At present, most of the aluminum alloy products such as 5083, 5086, 5454 and 5754 are used. In
LED Aluminum PCB is composed of the circuit layer (copper foil layer), thermal insulation layer and the metal core layer. Circuit layer require great current-carrying capacity, thus should use thicker copper foil and generally the thickness is from 35um to 280um; Thermal insulation layer is the core technology of aluminum PCB, it is usually made up of special ceramics and fill special polymers, with small thermal resistance, good viscoelasticity, and has thermal aging ability, and can be able to withstand mechanical and thermal stress. Thermal insulation layer of IMS-H01、IMS-H02 and LED-0601 and other high-performance aluminum PCB are using this technology, which has the extremely good thermal conductivity and high strength electrical insulation;
The best way to find an answer for this is to contact a metals supplier for quote on similar bar product. I was going to suggest that you look in the McMaster-Carr online catalog but I looked a moment ago and they have dropped 7068 aluminium alloys plate in favor of 7050, also a superior aluminum alloy. They still carry 7075 which is somewhat weaker but still better than 6061 aluminium alloys plate and 2024 aluminium alloys plate. You can contact Kaiser-Tennalum to find a distributor for 7068
There is no doubt that Aluminum in its pure state is a universal metal that is utilized in an array of applications. However, when aluminum is combined with other elements, making what is known as an aluminum alloy, its broad range of applications is extended even further.
Aluminum alloy 7075 is an aluminum alloy, with zinc as the primary alloying element. It is strong, with a strength comparable to many steels, and has good fatigue strength and average machinability. It has lower resistance to corrosion than many other Al alloys, but has significantly better corrosion resistance than the 2000 alloys. Its relatively high cost limits its use to applications where cheaper alloys are not suitable.
Aluminum alloy is one of the most widely used nonferrous metal structural materials in the industry. With the rapid development of industrial economy, the demand for aluminum alloy welded structural parts is increasing day by day. At present, aluminum alloy is the most widely used alloy.
