**What is BS 1748-6 - Determine tin in copper alloys by nickel coil reduction method about?**

BS 1748 is a British Standard on testing methods for the analysis of copper alloys.

BS 1748-6 is the sixth part of the BS 1748 series that discusses the determination of tin using the nickel coil reduction method for the analysis of copper alloys. Copper alloys are metal alloys that have copper as their principal component. They have high resistance against corrosion. The best-known traditional types are bronze, where tin is a significant addition, and brass, using zinc instead.

**Who is BS 1748-6 - Determine tin in copper alloys by nickel coil reduction method for?**

BS 1748-6 on determining tin in copper alloys by nickel coil reduction method applies to:

Manufacturers of copper and copper alloys
Tin manufacturers
Product design engineers
Quality testing personnel

**Why should you use BS 1748-6 - Determine tin in copper alloys by nickel coil reduction method?**

A silvery metal resists corrosion even at high temperatures. Nickel resists corrosion and is used to plate other metals to protect them. It is mainly used in making alloys such as stainless steel. Nichrome is an alloy of nickel and chromium with small amounts of silicon, manganese and iron.

BS 1748-6 provides you with the principle of tin in which the sample is dissolved in a mixture of nitric and hydrochloric acids. Tin is precipitated as the hydroxide, using iron hydroxide as the collector, then determined iodimetrically after reduction with nickel.

BS 1748-6 gives you the method with a range from 1.0 to 14.0 per cent tin. This helps you in the analysis of copper alloys. BS 1748-6 exemplifies silicon using the nickel coil reduction method for the analysis of copper alloys.
