As a you can find in the Material list, it already has this field populated with Generic values. To be super accurate, you will need to run this check for all materials. Please note, when you create a new material, it will only duplicate these values to the new material.
Metalix uses this density value (in gr/cm3) to calculate the material Weight in the Cutting Table
So in the Generic tables above, for Steel with a density of 7.8 gr/cm3, the weight of a 5mm 1500x3000 sheet will be 175.5 kgs
However, if your steel supplier gives you a different weight to what’s in the table, we need to work it backwards.
For example:
For 5mm Steel (250 Grade) , sheet size =3000x1500mm, Metalix calculates the sheet weight to be 175.5 kgs , but your Steel supplier tells you its actually 178.57kgs
So what we do to get the correct Density for this material is work out the gr/cm3 (what Metalix uses in their calculation):
Length x Width x thickness
300cm (3000mm) x 150cm (1500mm) x 0.5cm (5mm) = 22500 cm3
And now the weight:
178.57 kgs = 178570 g
= 178570g / 22500 cm3 = 7.936 gr/cm3
So to test this, change this value in material table
And check the weight in the Sheet Data base
- Make sure to click “Recalculate all weights”
- Check that the weight for that sheet is the same as your sheet supplier has given you
- Now enter your Price per Kg
please note, this is 1 example. it is a great way to enter in new materials that are different from the standard Ali, Steel and Stainless. in this example above, the difference is about $30 per ton of material.
