Conductivity Differences Between 6061 and 6063 Aluminum
Typical for metals, aluminum is an excellent conductor of heat and electricity. It is lightweight, making it a popular choice in transmission lines over more conductive metals like copper.
Electrical Conductivity
At room temperature, the electrical conductivity of aluminum is about (35 to 37) x 107 S/m. However, this value may vary for the two alloys, but we suspect they are closely related, having little effect on their conductivity.
In fact, silver, copper and gold are the notable metals with more excellent conductivity than silver. However, aluminum remains a popular choice in electronics and electrical applications because of its cost and increased density.
Thermal Conductivity
Like other properties we have discussed, aluminum alloys 6061 and 6063 shares similar thermal conductivity. However, the 6063 slightly has better conductivity. This suggests the reason for its relatively lower melting point. It also responds to heat which affords it better weldability and formability.
Pricing and Options
Aluminum is generally a cost-effective metal. The low-cost accounts for one of the reasons for its everyday use in various manufacturing and industrial uses.
However, the aluminum 6061 is slightly more expensive due to its relatively superior mechanical properties and applications. The cost may vary depending on location, market conditions, the alloy's quality, supplier, etc.
6061 vs 6063 Aluminum: Which One to Choose?
Generally, Al 6061 is preferred for manufacturing and machining parts for the aerospace and automotive industries, shipbuilding, and manufacturing of other structural components.
On the other hand, Al 6063 is known as the go-to aluminum alloy for architectural designs, including window and door fittings, lighting fixtures, etc.
Moreover, the 6063 alloy is more appropriate for manufacturing processes requiring high temperatures because of its better thermal conductivity.
