Titanium - Almost as Inexpensive as it has Ever Been

Inflation Adjusted Historical Titanium Price since 1941 - in Pounds Sterling and US Dollars

Titanium is a metal used in a variety of industrial application, from aerospace to marine, due to its high strength-to-weight ratio, high corrosion resistance, fatigue resistance, and crack growth resistance.  So I decided to examine the long term price history and inflation adjusted historic price of this industrially important metal.

The annual average titanium price was estimated from the price data for titanium sponge metal from 1941 to 2010 which came from the US Geological Survey.  The historical UK Pound to US Dollar exchange rate data came from Lawrence H. Officer, "Dollar-Pound Exchange Rate From 1791", MeasuringWorth, 2011 at www.measuringworth.com/exchangepound/.  The prices were adjusted for inflation by converting the nominal price into the equivalent in 2011 US Dollars and 2011 GP Pounds Stirling.  The US inflation data came from the historical CPI from the US Department of Labor.  The UK inflation the data came from Grahame Allen (2011) "Inflation: the Value of the Pound 1750-2011" Economic Policy and Statistics Section, Research Paper 12/31, House of Commons Library, UK.  From this you get the following results shown in the chart below.

The doted lines are the unadjusted nominal annual average titanium price, and the sold lines are the inflation adjusted titanium price. The first thing that becomes obvious is that the unadjusted titanium price was at its lowest in the in late 1961’s till the early 1970’s in both US Dollars and Pounds Sterling at approximately $1,040 and £2,900 per a metric tonne respectively. Additionally the nominal price peak occurs in 1981 and 2006 at approximately $8,400 and £17,000 in 1981 and $11,000 and £23,000 in 2006 per a metric tonne respectively.


However when you examine the inflation adjusted titanium price, you notice that its lowest prices occurred in 2003 in both US Dollars and UK Pounds Sterling at approximately $5,500 and $9,000 per metric tonne respectably.  The closest the inflation adjusted price came to those lows in both currencies, occurred in 1992 and 2010 approximately at $7,500 and £13,200 respectively.  The inflation adjusted titanium price experienced a constant fall until the early 1960’s whereupon it stabilised until the late 1970's.  This can be more easily seen in the chart below which only shows the inflation adjusted price on a linear axis (non logarithmic, unlike the first chart).

As it came be seen the general trend in the inflation adjusted prices was a steady decrees until the 1960’s where it stayed relatively constant (by historic standards) until the present day.  Even though there was a rapid increase in the real price in the late 1970’s, which peaked in the early 1980’s, it was nowhere near the inflation adjusted price before the late 1950’s.

Using the price in 1941 as a baseline, the inflation adjusted titanium price in UK Pounds and US Dollars was indexed.  This clearly shows how much the real price of titanium has dropped since the 1940’s.  By the bottom in the price, which occurred in 2003, it was approximately 4.88% of the price in 1941.  Even with the recent rally in the inflation adjusted price, by 2010 the price was still only just over 6% of that in 1941.

Even the relative price changes since the 1970’s show that by 2010 the inflation adjusted titanium price is still relatively cheap since that time.  This can be easily seen in the chart below, were the inflation adjusted titanium a price was index to that from 1975.  The price in 2010 was just under 40% of the real price in 1975 and reached a maximum in 1981 of twice compared to 1975.

So from a historical perspective, once inflation has been accounted for the price of titanium is almost as cheap as it has been in the last eighty years.  Even compared to the real inflation adjusted prices in the 1970’s the price by 2010 is below the historic average of that period.
