Installation/Set-Up Challenges for Aluminium Fasteners to Specification
When using aluminum fasteners to specification, some common installation or setup challenges may include:
Galvanic Corrosion: Aluminum can experience galvanic corrosion when it comes into contact with dissimilar metals, such as steel or stainless steel fasteners. This can lead to premature corrosion and failure of the fastening system.
Softness: Aluminum is a relatively soft metal compared to steel, so care must be taken to avoid overtightening the fasteners, which can lead to stripping of threads or deformation of the fastener.
Thread Galling: Aluminum fasteners are more prone to thread galling, which is the seizing of threaded components during installation due to friction and adhesion. Proper lubrication and careful handling during installation can help prevent this issue.
Differential Thermal Expansion: Aluminum has a higher coefficient of thermal expansion compared to steel, so considerations must be made for temperature variations that may affect the fastening system's performance.
Preventative Measures: To address these challenges, it is recommended to use fasteners specifically designed for use with aluminum, such as those with coatings or treatments to prevent corrosion, as well as following manufacturer's guidelines for torque values and installation procedures.
By being aware of these challenges and taking appropriate precautions, such as using compatible fasteners, lubricants, and installation techniques, you can minimize the risks associated with using aluminum fasteners in your applications.
