What's all the fuss about TH72M?

TH72M is the technologically advanced alloy developed by DAC and used in the outdoor adventure equipment industry wherever maximum strength with minimum weight is required. All the best quality lightweight tents use DAC tent poles made from TH72M.

ONLY Helinox products are engineered from TH72M.

One large step

Material science gradually evolves toward better solutions, but sometimes a major step is achieved that sets the new mark by which others measure their own performance. TH72M is a “quantum step” of progress for advanced lightweight material science.

How far ahead?

TH72M dominates the lightweight world like Michael Phelps has dominated the Olympic swimming pool. In fact, if it were a 200 meter swimming race, TH72M would touch the wall half a pool length in front of the nearest rival - that’s the extent of the TH72M advantage where strength to weight ratio is the measure of performance. TH72M is exclusive to DAC and Helinox products.

The "best" of ingredients

There is no “best” material element. Pure titanium has unique qualities but it is actually no stronger than steel - just 45% lighter. The best performing materials are a blend of various components that are combined to form an “alloy”. When titanium is carefully combined with silicon, iron, manganese, chromium, zinc, magnesium, copper and aluminium, the resultant alloy has qualities of strength and lightness well beyond any single component.

As any “Master Chef” will tell you, it’s not just using the best ingredients that matters. Skilled processing and preparation decides which is "great" and which is simply "good". In the world of high tech metallurgy, that means heat treatment procedures and forming processes. Extrusion is a process of “squeezing” metal past forming dies to create the shape and to compress the material for increased strength and hardness. DAC has a thirty year history of leadership in the development of high pressure alloy extrusion processes. Only DAC has the specialist machinery developed "in house" to cope with the extreme high pressures and deliver ultra fine tolerances. 

Over the barriers

DAC engineers have worked closely with metal producers for several decades to develop improved alloy blends. Apart from reaching new heights of strength, TH72M broke through a development barrier that has eluded industry for many years. The phenomenon of “stress corrosion cracking” (SCC) arises in very thin lightweight sheet or tube. The grain structure of the alloy can break down to produce a “cracking” effect - substantially weakening the material.  

This meant it was necessary to produce alloy tubing with thicker walls to avoid the SCC problems. The thicker walls provided no increase in overall strength - just extra material, cost and weight.

TH72M is an incredibly strong material that is also largely free of SCC characteristics. That means TH72M can be used to produce alloy tubing that is “thinner walled” than ever before. The result is tubing that is considerably stronger (because of the superior strength of TH72M) and considerably lighter (because the wall thickness can be reduced without SCC problems).

Looking after the environment

TH72M is the first ever aluminum based alloy that is anodized (ie colour coated) by a process that doesn't use environmentally harmful acids. DAC's unique "green anodizing" process has attracted world wide interest and is now the subject of considerable study. DAC's innovative approach might eventually reduce pollution throughout industry. In the meantime, your choice of TH72M is an environmentally responsible decision.

TH72M is the world’s best material for all outdoor adventure equipment.

Carbon Fibre?

Carbon fibre or "graphite" is a very light weight material that can produce excellent strength to weight characteristics - similar to high tech aluminium alloys. Carbon fibre, however, is inherently brittle and lacks the robustness required for the rigorous outdoor environment. A small localized impact can produce a tiny stress concentrating crack which can later become the site of a sudden dramatic failure without any warning. The image of an F1 race car hitting the fence and shattering into pieces is a good illustration of carbon fibre’s limitations.

Experienced outdoor adventurers avoid carbon fibre equipment where an unpredicted dramatic failure would be a major inconvenience or dangerous to life and limb. TH72M is the first choice for ultra light weight, incredible strength and robust reliability.
