EDITOR’S CHOICE A BRAZE NEW WORLD MORGAN ADVANCED MATERIALS SAFE, RELIABLE AND SUSTAINABLE SPACE EXPLORATION The space industry is growing fast and is predicted to be worth over a trillion dollars by 2040. Edward Arata, Brazing Engineer at Morgan Advanced Materials’ Braze Alloys Business, explains how braze alloys play their part in safe, reliable and sustainable space exploration. The saying goes “one small step for man, one giant leap for mankind”. This famous phrase, uttered by Neil Armstrong, is the perfect advertisement for space exploration and its importance to the future. Less than a century old, space exploration has come on leaps and bounds since the first artificial satellite, Sputnik 1, was propelled into space in 1957. Since then, the world has witnessed marvels such as landing on the moon, the space shuttle programme of the 1970s, and the launch of the International Space Station. 24 PECM Issue 38 The importance of these missions and their subsequent value is immeasurable. While many might not realise on a day-to-day basis, space exploration has improved lives and the global economy no end. This includes simple weather forecasting, broadcasting TV and radio, predicting natural disasters, monitoring for fertile land, forecasting sea level patterns, and even aiding research in muscular atrophy. external opinion though, there are internal operational challenges. Namely, space exploration needs to become safer and more sustainable. A huge part of solving this challenge is in brazing alloys. A BRIEF HISTORY ON BRAZING IN SPACE It’s little wonder then, that this industry has significant value. The space industry was reportedly worth $384 million USD in 2017, growing at a rate of 7.4 per cent. According to Morgan Stanley, it sees the industry growing to be worth $1.1 trillion USD by 2040. In simple terms, brazing joins two metals by heating and melting a filler (alloy) that bonds to the two pieces of metal and joins them. The filler must have a melting temperature below that of the metal pieces. However, there are challenges. Many believe that the millions of dollars and resources used to explore space could be better used on immediate threats to society like clean water, famine, poverty and more. Outside of The use of braze alloys in space equipment is mission critical, as they allow sensors to be mounted as close as possible to engines to measure and monitor output and feed data back to operators.
