Frequently Asked Questions
Why choose brass fasteners over stainless steel?
Brass offers three main advantages stainless steel does not: high electrical conductivity (important in grounding and electrical terminals), non-sparking behavior (required in explosive atmospheres such as petrochemical and grain handling), and traditional decorative appearance. Brass is also fully non-magnetic, which matters in some scientific and medical instrumentation. Steel is stronger, so brass is generally used in low-load, specialty applications.
What is the difference between brass and bronze fasteners?
Brass is primarily an alloy of copper and zinc. Bronze is primarily an alloy of copper and tin (sometimes with phosphorus, aluminum, or silicon added). Bronze is generally harder and more corrosion-resistant in marine environments than brass, and phosphor bronze is often specified for spring and marine applications. Brass is more common and more economical.
