In this sector you can calculate the dimensions like width or diameter, length or thickness (gauge) or the weight by given dimensions of copper and copper alloys. You have to give the values for 3 properties and the 4th value will be calcualted.
The value to be calculated has to be marked with a question mark (?) Be aware that the figures especially for the copper alloys are only approximate.Values are from datasheets from the website of Aurubis Stolberg

In this sector you can calculate the dimensions of tubes like width or diameter, length or thickness (gauge) of the walls or the weight by given dimensions of copper and copper alloys. You have to give the values for 3 properties and the 4th value will be calculated. For example you can calculate the thickness of a tube wall if you know the weight, the outer diameter and the length.The value to be calculated has to be marked with a question mark (?). Be aware that the figures especially for the copper alloys are only approximate. Values are from Datasheets from the website of Aurubis Stolberg

This is a special calculation mainly used for flat products. It shows a kind of strip length which is possible by rolling a cake of copper or copper alloys. The specific strip length is a value which is often connected to efficiency. Even if this figure is normally connected to rectangular dimensions, it can be used roughly for round. You have to give the values for 3 properties and the 4th value will be calculated. The property to be calculated has to be marked with a question mark (?) Be aware that the figures especially for the copper alloys are only approximate.Values are from datasheets from the website of Aurubis Stolberg

In this section you can calculate which energy is necessary to heat a certain amount of copper or copper alloys from a lower temperature to a higher temperature. The calculation for pure copper also takes into consideration melting point, melting energy and specific heat both for solid and liquid phase . Because of the lack of exact values for copper alloys the results are only correct for the solid phase (melting point of 100000 C) You have to give the values for 3 properties and the 4th value will be calculated. The property to be calculated has to be marked with a question mark (?) Be aware that the figures especially for the copper alloys are only approximate.Values are from datasheets from the website of Aurubis Stolberg

In this section you can calculate the flow of thermal energy through a piece of copper if both sides of the copper or copper alloy material have different temperatures. The values are calculated on the base for the specific thermal conductivity at room temperature. You have to give the values for 3 properties and the 4th value will be calculated. The property to be calculated has to be marked with a question mark (?) Be aware that the figures especially for the copper alloys are only approximate and this is only a calculation of thermal conductivity and not for heat transfer betwenn two liquid media.

In this section you can calculate electrical values for copper and copper alloys. So you can calculate the voltage drop through a wire with a certain diameter when a certain current is applied. The value are calculated on the base for the specific electrical conductivity at room temperature. You have to give the values for 3 properties and the 4th value will be calculated. The property to be calculated has to be marked with a question mark (?) Be aware that the figures especially for the copper alloys are only approximate as they depend e.g. on the phosphorus content. So they may be different from producer to producer.Values are from datasheets from the website of Aurubis Stolberg

Here the thermal expansion in length can be calculated from the original length and the temperature difference. There is no correction for illogical values (e.g. above melting point) - so examine if your input is correct. You have to give two values and the third will be calculated. The property to be calculated has to be marked with a question mark (?) Be aware that the figures are only approximate and with one property value along the whole temperature range.
