Copper and Aluminum Price Calculation

The material price for cables and wires is usually based on a copper price of 150.00 EUR/100 kg. For invoicing, as copper surcharge – the difference to the daily copper rate will be calculated.

Formula for calculating the copper surcharge:

DEL
The DEL (German electrolytic copper for guiding purpose) is the Stock Exchange Quotation for 99.5% pure copper. The value is given per EUR/100 kg in the economic part of daily newspapers.

Example:
DEL quotation = 194.29
100 kg copper cost 194.29 EUR and
1% delivery charge is added to the daily quotation for cables and wires.

Copper basis
In our catalog, for almost all cables and wires, a certain portion of copper price is already included.
Standard cables - copper basis = EUR 150.0/100 kg
Telephone cables - copper basis = EUR 100.0/100 kg
Power cables - copper basis = EUR 0 /100 kg (copper base = 0)

Copper value
The copper value is stated in our catalog. It is the copper weight of a cable or a wire.

Example:
JZ-500 8 x 0,75 mm², Part-No. 10040
Copper value 58 kg/km

DEL: 194,29 EUR/100 kg (assuming value)
Copper basis: 150.0 EUR/100 kg Copper value 58 kg/km

The net price including copper is calculated as follows:
Gross price
/ Individual discount
+ Copper surcharge

Calculation examples:
Assumption: 
•   DEL-Quotation 194.29 EUR/100 kg for copper
•   Daily rate 173.84 EUR/100 kg for aluminium
•   Individual discount, e.g. 20%
