Wire & Components · CCA
Copper-Clad Aluminium Wire
Every one of the nine catalogue listings names the same three winding wire options — copper, aluminium, and copper clad aluminium. This page is about the third: a wire with an aluminium core and a copper skin. Two facts sit behind it and are kept separate on this page: the listings name CCA as a winding option on every model, and the company profile describes an enameled wire plant among its plants. The source of the wire for a specific order is confirmed per project, in the quotation.

The wire options above appear verbatim in each listing’s parameter text. No cost ranking of the three wires is stated in the listings, and none is printed here.
01 The Material
What copper-clad aluminium is
Copper-clad aluminium (CCA) wire is drawn from a bimetallic rod: an aluminium core metallurgically bonded with a copper layer at its surface. The construction exploits a piece of physics — at the surface of a conductor is where connections are made and where, at higher frequencies, current prefers to travel — while the aluminium core keeps weight down. In a motor winding, CCA’s practical points are its copper surface for termination and soldering behaviour, and a weight below an equivalent copper winding, against a conductivity below copper’s that the winding design must allow for.
Within the catalogue, CCA is not an exotic option: it is one of the three standard wire choices written into every catalogue listing. The listing itself states the option, not the source — whether a specific order’s CCA wire comes from the enameled wire plant the company profile describes is confirmed in the quotation for that order. The enameled wire page explains the two facts separately; the copper vs aluminium windings guide sets CCA in the full three-way comparison.
02 Choosing
When CCA is the right winding
| Choose CCA when | Your programme needs copper-like termination behaviour — typically machines where pure aluminium’s size penalty or termination handling is unwelcome. |
|---|---|
| Choose copper when | Efficiency, temperature rise or the most compact frame governs — see the comparison guide. |
| Choose aluminium when | The winding design has room for the larger conductor aluminium needs for an equivalent resistance target — see the comparison guide. |
| How to order | Name the wire in the enquiry — ‘XM-8058-1, CCA winding, 220–240 V, 50 Hz’ is a complete instruction. The quotation prices the named wire; alternatives can be priced alongside. |
One discipline applies to all three wires equally: the wire named in the quotation is the wire in the motors. Do not rely on surface appearance to identify a wire at incoming inspection — a copper-coloured surface does not by itself distinguish CCA from copper. Verify against the approved sample and the batch documentation that names the wire. (This is general inspection practice, stated as background — it is not a procurement basis for any specific order, which is the quotation.)
03 Questions
CCA wire, answered plainly
Is CCA available on every model, or only some?
Every model — the three wire options are stated identically in all nine catalogue listings, from the 25–90 W spin motor to the 80–220 W pair.
Can I buy CCA enameled wire as a standalone product?
The company profile describes an enameled wire plant as one of its plants, and the catalogue documents CCA as a motor winding option; standalone wire supply is a separate question, confirmed per enquiry, as set out on the enameled wire page.
Does CCA change the motor’s published parameters?
The listings state one parameter set per model with the wire as a buyer’s option. Any performance consequence of the wire choice for your duty is addressed in the quotation discussion — in writing, before order.
