How do I differentiate between different types of installed wire lock/safety wire on planes?

Monel is more expensive than stainless steel so it's use is limited to where it is an advantage, mainly in high temperature applications such as securing engine accessories, piping etc. If the locking application is not in a high temperature, high humidity, high oxidisation area, then it's probably stainless steel.

There are chemical tests you can do on small samples using acids and reagents but you asked about an installed lock. The only way I know for testing an installed lock is to polish it. Monel is duller than stainless steel and does not polish to a shine so the quick way to tell is to try to polish a piece of it with a cloth. If it shines up, it's stainless steel. If it doesn't, it's monel.

Aircraft Lock-wire

 

Aircraft Lockwire

When you’re working on aircraft, it’s often not enough to securely bolt materials together, not when these materials will be subjected to the vibrations and stresses of flight. That’s where lockwire comes in, and that’s where Jaco Aerospace comes in. We are one of the largest distributors of lockwire worldwide, and we have an extensive inventory of safety wire of all materials and sizes.

 

Buying lockwire from us online is simple. Just choose the material you want from stainless steel, titanium, copper, brass, nickel, or alloys of the above. Select the diameter you need, and place your order to get our high-quality lockwire delivered as soon as tomorrow!

 

Using this safety wire to secure bolts is simple, too. In just a few minutes, you can learn the technique to lock wire around bolts so that when they try to come loose, the wire will counteract this force, securing them as firmly as a lock. Wire used in this way makes aircraft safer, and when you buy lockwire from Jaco Aerospace, you’ll be protecting your bottom line, too, thanks to our low prices. All of our lockwire products are individually labeled with the wire diameter, specifications, type of material, and lot number to provide for easy identification and complete traceability of the wire.
