In chapter 5 lesson 15, you’ll learn about anodizing and other non-coated finishes that enhance the durability, appearance, and functionality of your parts without adding a physical layer of material. Jake explains how anodizing works, an electrochemical process that creates a protective oxide layer on aluminum, improving corrosion resistance, surface hardness, and color options through dyes.

You’ll also learn how anodizing differs from additive coatings like powder coat, how it impacts electrical conductivity, and why certain materials use similar processes such as passivation for stainless steel or black oxide for carbon steel. Jake covers design considerations like when anodizing slightly changes part dimensions, and when to avoid welding or machining until after the process. The lesson wraps up with a walkthrough of how to select anodizing or powder coating finishes in SendCutSend’s ordering system and what to expect when your parts arrive.

What You’ll Learn:

• What anodizing is and how it protects and strengthens aluminum
• The difference between anodizing and additive finishes like powder coating
• How anodizing affects corrosion resistance, hardness, and conductivity
• When to use anodizing, passivation, or black oxide based on material type
• How anodizing slightly alters dimensions and when it matters for design
• Why anodized parts should not be welded and how to plan post-processing
• How to select anodized or powder-coated finishes in SendCutSend checkout
