Small Parts has added a line of Aluminum fasteners and here are some of the benefits that they will
add: Resistance to atmospheric corrosion: Because of its tendency to form a protective oxide coating upon exposure to the
atmosphere, aluminum needs no further treatment in ordinary environments. Special alloys and anodic coatings are available
for application in extra-corrosive environments.
Nonstaining: The oxides of aluminum are colorless and such corrosion products as may occur will not mar the finish of
products or assemblies. The surfaces of aluminum fasteners react with oxygen in the air to form a hard, colorless oxide
coating which seals, protects and prevents the fasteners from staining the materials they are joining. When you use
aluminum fasteners in your finished products, you can expect these fasteners to retain their good appearance for many
years. The potential hazard of galvanic corrosion between dissimilar metals is eliminated when aluminum fasteners are
used to fasten aluminum components.
Strength: Aluminum possesses the best strength-to-weight ratio of any metal. It can be made stronger than mild
steel. Aluminum fasteners are strong enough to be used in high-speed, automatic production lines.
Lightness: Aluminum weighs about one-third as much as mild steel. Although weight is a significant factor in
most applications for fasteners, lightness can reduce costs and facilitate movement into, through and out of the manufacturing plant.
Compatibility with aluminum: It is standard practice to fasten aluminum with aluminum in order to minimize the danger of galvanic corrosion.
Conductivity: Aluminum offers high conductivity at a low cost. Electrical utilities have switched over to the
exclusive use of aluminum for the transmission and distribution of power. Aluminum fasteners are used to
connect power lines to transmission towers, for accessories and in substations. Aluminum threaded
fasteners are used to connect bus bars and service drop cable in commercial and industrial power
applications, as well as for connectors and electrical contacts for the communication and electronics industries.
Nonmagnetic: Aluminum is the preferred metal in applications where magnetism may be a problem.
