nation of the fiber lens from debris. The laser windows feature Moh 9 hardness, a 10-5 scratch-dig finish, and can withstand steel splatter, flash, and debris. Providing a 1⁄4 wave transmitted wavefront, the windows can be used as debris shields on 1064-nm industrial cutting lasers from 4 kW and above. With A/R coatings on both sides, the fiber laser windows provide more than 99.5% transmission at 1.07 microns, with more than 90% at 650–670 nm. They are available in 1- and 2-in. sizes. Sapphire C-plane windows coated on one or two sides are also offered. Laser Research Optics laserresearch.net (888) 2395545 Cutting Machine Useful for Art Projects The company’s MiniCut CNC plate cutting machine features a compact design, is lightweight, and can easily be moved to indoor or outdoor working environments. Useful for metalworks up to 2 in. thick, the machine has two options for cutting — either with a oxygen or plasma torch. It can cut various types of material as well as handle intricate or simple designs, such as signs and lettering. The machine offers precise cutting for many art-related projects. Otto Arc Systems, Inc. ottoarc.com (800) 8782487 Hardfacing Products Available for Railroad Frogs Postalloy® FrogTuff hardfacing product for manganese steel railroad frogs and crossings is offered as flux-cored wire and as a flux-coated electrode. Under severe impact, such as hammering or pounding from continuous rail traffic, the full austenitic weld deposit quickly becomes tougher and harder. The flux-coated electrode operates on either AC or DC reverse polarity. The arc is smooth and stable with low spatter loss. With a tensile strength of 125,000 lb/in.2, a yield strength of 80,000 lb/in.2, and a 34% elongation, the hardness as deposited is 15–22 Rc and work hardens up to 55 Rc. The company has also introduced a self-shielded flux-cored wire version of the product. It produces high-strength, crack-resistant deposits that are tough, ductile, and work-harden rapidly.
