Monel 400 tube pricing moves with LME nickel and copper rates, but size, wall thickness, and finish plays the equal role in the final quote. Fitlok manufactures and exports ASTM B163 UNS N04400 Tubing directly, so pricing reflects mill cost rather than a trading markup, whether you need a single piece or a full export shipment.
