In Brazil, PAL is used in conjunction with the 525 line, 59.94 field/s system M, using (very nearly) the NTSC colour subcarrier frequency. Exact colour subcarrier frequency of PAL-M is 3.575611 MHz. Almost all other countries using system M use NTSC.n Brazil, PAL is used in conjunction with the 525 line, 59.94 field/s system M, using (very nearly) the NTSC colour subcarrier frequency.

Pure Tungsten (EWP) is typically used in welding aluminum. This provides the stable arc with AC welding and can be used with either Argon, Helium, or mix shielding gas. Pure Tungsten electrodes are marked by a green tip. Pure tungsten has the highest consumable rate of all the types, but they are cheaper too.
1 Vanadium foil is used in cladding titanium to steel. 2  Vanadium-gallium tape is used in superconducting magnets (175,000 gauss). 3  Vanadium pentoxide V 2 O 5 is used as a catalyst in manufacturing sulfuric acid (via the contact process) and maleic anhydride.4  It is also used in making ceramics.
