Aluminium (Al) — 10-Year Trends

As of 2026-09-25 · the last 10 years

Aluminium’s research intensity sits at about 89% of its own all-time peak, a level reached within this window in 2019.

Research intensity ran from about 96% of the element's own all-time peak in 2016 to about 89% in 2026 — a steady decline, and the all-time peak (2019) falls inside this window. Over the same span its share of research attention across all elements fell. Among the 118 elements, aluminium has a larger-than-average research literature.

The number of papers involving the element rose from about 45,209 in 2016 to about 81,041 in 2025 (1.79x). That is slower than the literature as a whole grew over the same years, so the element lost ground in the wider body of research even as its own count rose.

The core of aluminium’s recent research is found in Aluminium Alloy Joining and Microstructure Evolution, which accounts for about 45% of the element's recent research. This community focuses on friction stir and spot welding of specific alloys, analyzing how the welding process alters the microstructure and mechanical properties of the joints. Aluminium is one strand of a broader community, with about 13% of its papers involving the element. The share has remained steady over the last two periods. A 2023 review of recent trends in aluminium 7075 alloy and its metal matrix composites for aircraft applications, cited over 260 times, anchors this field.

A second major area is Aluminum Alloy Fabrication via Arc and Laser Processes, representing about 12% of the element's recent research. These papers focus on wire arc and laser-based additive manufacturing and welding, analyzing energy deposition, residual stress, and microstructural outcomes. Here, aluminium is a minor presence in a much larger community, with only about 2% of its papers involving the element. While the share is classified as steady, it has grown from 9% to 12% over the window. The most cited work in this area is a 2017 paper on 3D printing of high-strength aluminium alloys, cited over 2,900 times.

A smaller but distinct community is Anodized Aluminum Oxide Membranes and Photonic Templates, holding about 3% of the element's recent research. This work focuses on hard anodizing processes, oxide film formation, and the use of porous templates for photonic crystal applications. Aluminium is one strand of a broader community, with about 22% of its papers involving the element. The share has remained steady, though it dipped slightly from 4% to 3%. A 2021 paper revisiting anodic alumina templates from fabrication to applications, cited over 270 times, is a key reference here.

Overall, the composition of aluminium’s research has remained remarkably stable. The three named communities hold their relative positions, with the remainder of the literature—comprising other smaller groups—holding about 40% of the share. The most cited paper of the window, a 2022 study on self-assembled monolayers directing a LiF-rich interphase toward long-life lithium metal batteries, cited over 960 times, belongs to a community not detailed in this element’s primary roster but highlights the element’s role in broader battery electrolyte research.
