FPV consists of a few material types, understanding the benefit and liability for each is important. Please refer to this page for more information on our product and use in general.
Nylon vs Steel vs Aluminum vs Titanium
When it comes to fasteners these material types come up a lot.
- Nylon: Very common, low weight, not strong at all (plastic), used for low impact, non-structural elements. Most commonly a component in the stack.
- Nylon is not conductive and in many cases this is very important as certain elements on the stack may have a "hotness" that makes use of steel or other conductive material a bad idea.
- Steel: Very common, very strong, heaviest of the options. Good for motor mounting, frame construction, stack.
- There are several variations in steel such as stainless, grade variations, and coatings. Generally we see A2 Stainless being very common in FPV.
- Steel is conductive, just a reminder.
- Aluminum: Less common as a screw or fastener, very common as a standoff. Light weight, will deform (malleable), medium strength, tends to stretch over time. Great in some applications and bad in others. The anodizing process allows aluminum to be "colored".
- Aluminium is conductive to a lesser degree, 59% the conductivity of copper to be exact. Be careful when using aluminium parts around any components with a "hotness"
- Titanium: Less common, very strong, low weight, great all around, costs more. Titanium is similar in strength to steel but comes in close to 1/2 the weight! These parts cost much more to product however.
- Titanium costs about 6 times more to produce than steel
- Titanium is not good at dissipating heat.
- Titanium is equal to that of common, low-grade steel alloys, but less dense
- Titanium is 60% denser than aluminium, but more than twice as strong
- Titanium is non-magnetic and a poor conductor of heat and electricity
- Titanium has a fatigue limit that guarantees longevity (in certain applications)
The Problem with Anodizing, especially Gold
Anodized aluminium tends to have mild variations in color or tint. So far none of the colors we have purchased displays this more than gold. In general they look good together, often separated by black carbon fiber or other hardware one will never notice. The fact remains, colors vary on these parts and gold seems to be displaying this more than other colors. If you are critical on matching a color or need to know about the current tint(s) please contact us.
