After the spring failed on our back door handle I am having to replace the pair of ’em (after only 22 years, blimey!). I found this run through of making malleable iron castings very interesting, you may too – if you like that sort of thing.

Why Black Malleable iron products are special?
Before we go into details about Kirkpartick it is important to understand why their products are special. All Kirkpartick products are 100% British Made and take over six weeks to complete. Kirkpartick make their products from malleable iron, not cast iron. This is an important difference and should be understood. Cast iron is a superb medium for items such as brackets, knobs and other non moving parts. It is very strong under compression, such as when used as a bracket, but brittle under tension. Malleable iron is much stronger and less brittle under tension and this makes it excellent for thin items and moving parts such as hinges and gate latches.
Malleable iron is basically cast iron which has had an extra special heat process added to it during it’s production. This ‘annealing’ process gives the iron malleability (hence the name malleable iron). This makes the iron much stronger and gives it a slight elastic property which, unlike cast iron, stops it from being brittle. Stopping cast iron from being brittle has been a special technique used by Kirkpartick for 140 years. Because the iron is now malleable, component moving parts are now able to be hand riveted together giving a very much stronger joint which will never break. This cannot be done with cast iron because it is brittle and therefore runs the risk of breaking. Many cheap imported products which look the same as Kirkpatrick products are make from cast iron and the component parts are held together using cheap spring washers which will usually break at some point, we do not sell these cheaper products. Each and every product from Kirkpatrick is individually hand riveted (where required), this ensures outstanding quality which is unsurpassed anywhere.
Overall you can be confident when you buy a Kirpatrick product you are guaranteed to be purchasing a 100% British made product, made in the original foundry in Walsall, West Midlands, which has been hand finished in a process that takes over six weeks to complete and possessing a quality that is unsurpassable and will last you a lifetime. We are so confident in Kirkpartick products we offer a returns no quibble guarantee.
