Free calculators for galvanic corrosion checking, resin mix ratios, and volumetric analysis. Tools for material selection, chemical mixing, and process engineering.
Galvanic Compatibility Checker
Check galvanic corrosion risk between any two metals. Shows potential difference, risk level, and mitigation strategies.
Resin Mix BOM Calculator
Calculate material quantities for multi-component resin systems. Supports mix ratios by weight or volume with waste factors and batch scaling.
Two-Part Mix Calculator
Quick ratio calculator for two-part adhesives, epoxies, and potting compounds. Enter any quantity and get exact amounts for both parts.
Volumetric LDR Calculator
Calculates the Limiting Draw Ratio for sheet metal deep drawing. Evaluates formability based on material properties and punch geometry.
Friction Coefficient Lookup
Look up static and kinetic friction coefficients for common material pairs. Includes dry, lubricated, and wet conditions.
Material Selection & Process Tools
Material compatibility and proper mix ratios are foundational to reliable designs. The galvanic checker helps avoid costly corrosion failures, while the mixing calculators ensure accurate material preparation.
