Types of Investment Casting Materials
Properties Comparison
When you pick materials for investment casting, you look at what they can do. Each alloy gives you different levels of strength, rust protection, and weight. You want parts that are very exact and have smooth surfaces. This helps your project work well.
Here is a simple chart comparing the top three alloys:
| Property | Stainless Steel | Aluminum Alloy | Carbon/Low-Alloy Steel |
|---|---|---|---|
| Mechanical Strength | Stronger than aluminum | Not as strong as steel | Not as strong as steel |
| Corrosion Resistance | Great because of chromium | Good, but not in tough places | Not as good as steel or aluminum |
| Weight | Heavier than aluminum | Much lighter | Heavier than aluminum |
Stainless steel alloys protect best against rust. They make strong parts that last a long time, even in hard places. Aluminum alloys help you make light parts that are very exact. Carbon and low-alloy steels are strong and exact for heavy jobs, but they are heavier and do not fight rust as well.
You should choose the alloy that fits your needs. This helps you get the right mix of strength, weight, and rust protection.
