men is met een groot tempo bezig de gehele wereld te elektrificeren. Dit gebeurt grotendeels met gebruik van koper. Je zou denken dat dit de komende jaren een gigantische kopervraag oproept. Of denk ik te simpel over zoiets??

Dat zou je inderdaad mogen denken, maar de koperprijs doet het slecht.

Optomec Releases Pure Copper Directed Energy Deposition Additive Manufacturing Process

Leading global supplier of additive manufacturing equipment and software Optomec announced the development of a pure copper Additive Manufacturing process using Optomec’s LENS directed energy deposition systems. Mr Tom Cobbs product manager for Optomec LENS systems said that “Pure copper is a big challenge for DED systems because of its high reflectance. The infrared wavelengths on most standard, laser-based AM systems are not readily absorbed by copper, making it difficult to establish a melt pool as the laser energy is reflected back into the source, causing all kinds of havoc. Our laser-based solution is virtually immune to any back reflection, so the laser can operate at full power on reflective surfaces without any difficulty. Optomec engineers have developed process parameters to account for thermal conductivity differences, as well as big changes in absorption and have demonstrated efficient DED builds with pure copper.“

Establishing a DED process for pure copper is particularly important for designers of heat exchangers in a variety of industrial applications in industries such as aerospace and chemical processing. The Optomec copper process is also applicable to alloys of copper such as bronze, brass and cupronickel.

India Becomes Copper Importer in under 2 years

The Print reported that India’s copper imports have risen sharply in the last year and a half. India, which was among the top five exporters of copper cathodes in 2018-19, became a net importer beginning 2018-19 as Vedanta subsidiary Sterlite Copper’s 400,000 tonnes plant in Thoothukudi, earlier known as Tuticorin, was shut down in May 2018 on the orders of the Tamil Nadu government, after violent protests by residents, who alleged that the factory was a health hazard.

India exported nearly 378,000 tonnes of copper cathodes 2017-18, 48,000 tonnes in 2018-19 and 7,000 tonnes in the first half of the 2019-20 financial year. On the other hand, India had imported just 36,000 tonnes of copper cathodes in 2017-18, 84,000 tonnes in 2018-19, while in the first half of 2019-20, the country has already imported 70,000 tonnes of copper cathodes.

China US Trade Negotiation News Supports Copper Prices

Copper prices touched their highest in more than two weeks as positive signals from the China US trade negotiations stoked hopes of improving global appetite. The most-traded copper contract on the Shanghai Futures Exchange advanced as much as 0.7% to CNY 47,410 (USD 6,735) a tonne, its highest since November 11. Benchmark three-month copper on the London Metal Exchange dipped to USD 5,870 a tonne, easing from a two-week high touched in the previous session.

US President Mr Donald Trump said that “The United States and China are close to agreeing on the first phase of a trade deal. They are in the final throes of work.”

The 16-month dispute has been weighing on global economic growth and demand for industrial metals, so signs of progress often support metals prices.

Iran Soon to Become World’s 7th Biggest Copper Ore Producer

Financial Tribune quoted National Iranian Copper Industries Company MD Ardeshir Sa'd-Mohammadi as saying that qith an annual production of 34.5 million tonnes, Iran is currently the world’s eighth biggest producer of copper ore in the world and that with the development of mineral explorations, the country will soon ascend to the seventh rank.

According to the official, Iran’s copper reserves make up 4.15% of the global copper reserves.
