Materials for
Custom Marine Parts
Selecting the right material is essential for marine components exposed to saltwater, humidity, mechanical loads and long-term outdoor use. BC Marine Tech works with a range of engineering materials for custom marine parts, helping match material properties with the application, environment and manufacturing requirements.
How to Choose the Right Material for Marine Parts
Corrosion Resistance
Suitable material selection for saltwater, humidity and demanding marine environments.
Strength & Load
Consider tensile, impact and mechanical loads according to the part’s application.
Weight
Material weight can influence overall component weight and system requirements.
Wear Resistance
Important for components exposed to friction, movement and repeated use.
Machinability
Material selection also needs to match CNC machining, precision requirements and part geometry.
