Lothar Walther Bi-Metal Barrels Are Lighter, and Shed Heat Better

Less weight plus better heat dissipation — Sound good? Here is an innovative barrel technology that promises worthwhile performance benefits for hunters or match shooters. Lothar Walther (LW) has developed a new bi-metal barrel system that cuts weight dramatically while promising significantly-enhanced heat dissipation.

Walther’s Ultra-Lightweight Barrels combine steel with lightweight alloys. This results in a significant weight reduction without the use of carbon fiber, epoxy binders, or other heat-retaining materials. Beginning as an LW50 stainless blank, the barrel is precision-machined to remove excess weight. An outer casing of light-weight alloys is machined and the two are fitted together without adhesives. Basically you end up with the steel inner barrel inside a larger-diameter fluted aluminum outer barrel (see diagram). This gives you the ‘best of both worlds’ — light weight for ease of carry, and thick diameter for rigidity and enhanced heat dissipation. Near the action, the barrel remains all-steel.

The barrels come pre-chambered in your choice of caliber/cartridge, from .22LR up to .338 Lapua Magnum. Walther chambers the barrel — but a gunsmith is still required to finish the shoulder so that the headspace is set correctly for your action. These barrels are not inexpensive. A typical bi-metal Walther Barrel runs $850.00 – $875.00, for barrel lengths from 22″ to 30″. Threading for a muzzle brake or suppressor (if desired) is normally included in that price.

Aluminum thermal conductivityWe haven’t tested one of these bi-metal composite barrels, but the potential for significant weight savings is obvious — aluminum is a lot lighter than steel. What’s more, a metals expert we contacted said that a bi-metal system employing fluted aluminum over steel, if assembled properly, could dissipate heat much better than steel alone (given the same diameter). Stainless steel has a thermal conductivity factor of 16. Aluminum has a thermal conductivity factor of 250.*

Our expert also pointed out that some other composite barrel systems on the market actually increase heat retention because they place insulating materials next to the inner steel barrel. (Carbon, Fiberglass, and Epoxy are all considered “insulating substances” as they have very low thermal conductivity*.) The LW system of aluminum over metal should avoid this mistake, our expert believes. Lothar Walther says: “Unlike solid steel barrels, this barrel sheds heat fast. VERY FAST!”

Half the Weight of Conventional Barrels
How much weight can you save? With a 1.200″ shank diameter and a muzzle diameter of 0.850″, the LW Ultra-Lightweight Barrel is less than half the weight of a standard varmint barrel of the same size. Walther claims its UltraLight Barrel can be “carried for long distances and stand up to heavy firing.” This, LW says, makes these barrels “perfect… for varmint and tactical uses”.

Pre-Chambered Ultra-Lightweight Barrels Available in .22 to .338 Calibers
Lothar Walther offers Ultra-Lightweight barrels in a full range of calibers from .22LR to .338. Each Ultra-Lightweight Barrel comes complete with chamber, crown, and breech threads. These barrels are fluted by the factory. If you order a LW Ultra-Lightweight barrel, Lothar Walter provides the services of a specialist trained in building guns with these barrels.

*Thermal conductivity is the quantity of heat transmitted through a unit thickness in a direction normal to a surface of unit area, due to a unit temperature gradient under steady state conditions. The factor values are based on this formula: W/(m.K) = 0.85984 kcal/(hr.m. °C). Here are thermal conductivty values for common materials: Aluminum, 250; Brass, 109; Steel (Carbon 1%), 45; Stainless Steel, 16; Carbon, 1.7; Brick dense, 1.3; Concrete (medium) 0.7; Epoxy, 0.35; Fiberglass, .04.
