Iron & Metal Alloys #5196464

Aluminum Alloy 6951 is predominantly used to manufacture fins for heat exchangers in the aerospace market. Since 6951 is a heat treatable alloy, it provides additional strength to the fins while increasing sag resistance. heat-exchanger This additional strength also allows the manufacturer to reduce the gauge and subsequent weight of the formed fin. Due to these important attributes, aluminum alloy 6951 is the preferred alloy for heat transfer units manufactured for the aerospace industry. Lynch Metals has the largest inventory of 6951 coil in the world. By stocking wide width coils in a multitude of gauges, Lynch will slit to your specific width and quantity within three to five days from order placement. Whether you require one pound or ten thousand pounds, Lynch Metals will provide you with the quantity you require when you need it. Since this material is stocked in O temper in gauges as light .003 and as heavy as .015, Lynch Metals has invested in special slitting equipment to insure a burr free, tight, uniform coil. Our three Goebel slitters, along with our two Ruesch slitters and our high production Kampf slitter, were specifically purchased to slit this unique product. Lynch Metals takes extra precaution when packaging your slit coil so you receive it in perfect condition. Our sophisticated foam packaging equipment provides a protective outer shell that fully encompasses the slit coil packed within a heavy duty cardboard box. Material is easily identified with your part number by our computerized labeling system.

Lynch Metals is the predominant distributor of Aluminum Alloy 4047 bare metal in foil, fin, and sheet in the world. This unique alloy is used in both the aerospace and automotive markets as a cladding alloy or filler material. As a filler material, aluminum alloy 4047 strips can be applied to intricate applications to bond two metals together. Alum-4047-(1)It is an excellent product for smaller production applications or for assemblies where the join is difficult to get to. In the case of smaller production runs, Lynch Metals is the preferred source since we can supply as little as one pound. Whether you require 4047 to be in coil or sheet form, we have the in house ability to slit, cut-to-length, or shear to the exact size you require. Our width and length tolerances are the tightest in the industry, therefore reducing your in-house scrap. Since our primary mill source produce only aluminum brazing sheet, we have available the thinnest 4047 in the industry. We can slit as light as .001 and as heavy as .125. In sheet form, we can supply material cut-to-length from .020 through .125. We can slit as narrow as .200 or as wide as 48 on our specialized slitters that only slit non-ferrous materials. Lynch Metals will supply a burr free, uniform coil that is tight throughout. Since light gauge 4047 aluminum alloy fin and foil is easily damaged while in transit, we take the extra precaution to package our material in foam when traveling a long distance. We also take great care in protecting our material when traveling shorter distances by packaging our material in wood boxes when needed. Our broad and comprehensive inventory of 4047 master coil is available in the following gauges: .001, .0015, .002, .003, .005, .010, .015, .020, .032, .063, and .125. We can also provide any additional thickness if a requirement approached an annual usage of 8 10, 000 pounds. Whether you need one pound or ten thousand pounds, Lynch Metals is the predominant supplier of Aluminum Alloy 4047 fin, foil, coil, and sheet product that will deliver what you need, when you need it.

No. 21 and 22 brazing sheet are typically used in Dip Brazing applications. No. 21 is one side clad and No. 22 is a two sided product, with each having a heat treatable core of 6951 and a cladding alloy of 4343. flux-brazing-alloys In Dip Brazing, air is excluded from the process since the parts are submerged in molten salt, thereby excluding exposure to air and subsequent oxidation. The molten salt functions both as a heat transfer medium and flux. The typical application of dip brazed alloys No.21 and No.22 is for parts where strength is required. The 6951 core is a heat treatable alloy, providing additional strength and offering the opportunity to save weight by down gauging. Many of the dip brazed parts find their way in heat transfer applications for the aerospace industry. Lynch Metals has the largest inventory in the world of these Dip Braze products. The material is stocked in both its Union, NJ and Anaheim, CA facilities in gauges ranging from .020 through .190.
