WIRE

-Round wire Ag 800‰, 925‰ sterling, 935‰ and fine silver 999‰ finenesses.

Round wire can be supplied in soft-annealed, hard-drawn and semi-hard-drawn physical state. The corresponding hardness values are listed in the table below. Specific hardnesses are also available upon request as special orders.

The sizes available range from a maximum diameter of 7mm to a minimum diameter of 0,20mm. For diameters over 7mm please refer to the section on this website dedicated to rods.

The standard interval sizes for La.Met round wires are as follows:
from ø 7,00 to 3,50mm: 0,25mm intervals - tolerance ± 0,06 – hanks internal ø 400mm.
from ø 3,40 to 1,00mm: 0,10mm intervals - tolerance ± 0,04 – hanks internal ø 200mm.
from ø 1,00 to 0,40mm: 0,05mm intervals - tolerance ± 0,01 – hanks internal ø 200mm or on reels.
from ø 0,35 to 0,20mm: 0,05mm - tolerance ± 0,006 – only on reels.

-Half-round wire Ag 800‰, 925‰ sterling, 935‰ and fine silver 999‰ finenesses.

Half-round wire can be supplied in soft-annealed and semi-hard-drawn physical state.

Half-round wire is understood as wire with a profile equiovalent to half of a cricle, thus the height is exactly half of the diameter. La.Met half-round wire is available in standard sizes from 6x3mm to 1,5x0,75mm with intervals if 0,10mm (referring to diameter) wound in hanks as per round wire above. Tolerance values are approx +/- 0,05mm.

-Square wire in 800‰, 925‰ sterling, 935‰ and fine silver 999‰ finenesses.

Square wire from rolling mill with rounded edges (only available in soft-annealed state) is manufactured in the following sizes: 8,7 – 8,0 – 7,4 – 6,8 – 6,3 – 5,8 – 5,35 – 4,95 – 4,55 – 4,2 – 3,9 – 3,6 – 3,3 – 3,05 – 2,85 – 2,65 – 2,45 – 2,1 – 1,95 – 1,8 – 1,65mm (approx tolerance +/- 0,10mm.) wound in hanks with internal diameter 240mm.

Square wire with sharp edges (available in soft-annealed and semi-hard states) is available in sizes from 6mm to 1,50mm with 0,10mm intervals. (approx tolerance +/- 0,05mm) qound in hanks as per the round wire above.
