What Is Aluminum Building Wire?

For over 100 years, utility end users have relied on aluminum building wire for efficient power transmission and distribution. The reasons are clear: aluminum is cost-effective and boasts a superior conductivity-to-weight ratio compared to alternatives like copper.

Modern aluminum alloys used in building wire offer exceptional conductivity, improved creep resistance, and increased strength, solidifying aluminum’s position as a reliable and cost-effective choice for electrical wiring.

What Are the Benefits of Aluminum Building Cable and Wire?

Compared to copper, aluminum building wire offers distinct advantages in several applications:

  • Lightweight Champion: During construction, every pound counts. While slightly larger than copper wire of similar conductivity, aluminum building cable weighs about half as much. This translates to significant weight reduction on large projects without compromising performance.
  • Cost-Effective Choice: Aluminum is often half the price of copper. While it may have slightly lower corrosion resistance, the substantial cost savings often outweigh this factor. For applications with minimal exposure to corrosion, aluminum cable becomes even more affordable, especially for large-scale projects requiring significant wire lengths.
  • Easy to Maneuver: Aluminum’s flexibility makes it easier to work with than copper, particularly for long runs and confined spaces.

Choosing the Right Wire

Remember, project specifics matter.  Consider the pros and cons of various building wire types to ensure they meet your needs.  In many cases, aluminum will be your project’s most practical, cost-effective, and durable choice. We’re happy to help you select the best option for your specific application.

What Are Some Common Aluminum Wire Building Applications?

Aluminum building wire is often used in electrical utility applications due to its exceptional conductivity-to-weight ratio, low cost, and workability:

  • Overhead power transmission lines
  • Local power distribution lines
  • Power grids
  • Commercial and industrial buildings and project installations
  • Houses and multi-family developments

With its lightweight durability, aluminum cabling has a place in the aerospace, automotive, construction, and transportation industries.
