Copper Nickel Alloys: 90/10 vs 70/30 Cupronickel Comparison

Copper Nickel Alloys: 90/10 vs 70/30 Cupronickel Comparison Copper-nickel alloys (cupronickels) are among the most important materials for marine and seawater applications. The two most common grades — 90/10 Cu-Ni (C70600) and 70/30 Cu-Ni (C71500) — offer exceptional resistance to seawater corrosion, biofouling, and erosion. This guide compares these two alloys to help you select […]

Steel Pipe Support Spacing: How to Calculate for Your Project

Steel Pipe Support Spacing: How to Calculate for Your Project Proper pipe support spacing is critical for the structural integrity of any piping system. Supports that are too far apart cause excessive sag, stress concentrations at joints, and potential failure. Supports that are too close together waste material and labor costs. This guide explains how

Stainless Steel Passivation: Why It Matters for Corrosion Resistance

Stainless Steel Passivation: Why It Matters for Corrosion Resistance Stainless steel passivation is a critical post-fabrication treatment that maximizes the natural corrosion resistance of stainless steel. Despite its name, stainless steel isn’t completely “stain-proof” — it requires proper passivation to form the protective chromium oxide layer that prevents rust and corrosion. This guide explains why
